I'm all for repairability, but as labor costs go up and manufacturing costs go down, the window for which there is incentive to repair narrows.
e.g. there's no amount of repairability design that you could apply to a $3 light bulb which would encourage people to pay someone western wages to repair. I think we're better off lobbying for better standards to communicate the quality of a bulb's design. The whole reason we have crappy LED bulbs to begin with is because the $3 overdriven bulb with crap components jammed into a tiny enclosure looks like a better deal on the shelf than a bulky $20 bulb with a large heat sink and lower output.
And the labor required to do component level repair is wildly expensive and limited (YouTubers who do it on principle notwithstanding), even further narrowing that window.
If you could disassemble and diagnose a failing $3 bulb in 60 seconds, you wouldn't need to hire someone at western wages to fix it. But because it is glued together to not be taken apart, and there are no diagrams for how anything in it works or is put together, it isn't worth the time even if you have a station and equipment all ready setup and replacement component on hand. 95% of the time fixing electronics is just figuring out how they were put together in the first place so you can diagnostically trace along the circuit.
Not that I think lightbulbs are probably worth saving, but expand it to any other device which gets exponentially more complex and it is easy to see why they don't get diagnosed, not to mention repaired. With a board diagram I can point at a spot on the board and say "I should see 15 volts here", without a board diagram i gotta draw out and figure out how the power supply even works so I know what it is suppose to be outputting and then trace that all the way to the test point to make sure there isn't other crap inline before then that might change what I see.

Sure, I would. Maybe a lot of people on this forum would. But we're 0.0001% of people that use light bulbs. Our personal persuasions are pretty irrelevant in context. And most of the time it doesn't make financial sense for us to do it, it is just personally satisfying.
The vast majority of people have no interest in repairing their own electronics, period. If it is cheap to replace, they will just get a new one. If it was a big investment, then it's important enough to call a professional to fix. In the middle ground you've got people who will ask their handy nephew to try to fix it before they run out to the store, and he'll open it up and look for a blown fuse or a loose wire before giving up. The type of people who can do board level repairs are so rare as to be completely irrelevant to the waste stream of electronics.
Even if we repaired 100% of broken electronics, we'd only make a tiny dent in the volume of waste electronics. Most electronics simply fall out use before they ever break.
If they had board diagrams or schematics that nephew could do a lot more than simply look for a blown fuse or wire. Nobody looks deeper than that because they know it is a waste of time without any reference materials.
No it doesn't solve all the problems, but how many TVs now sit in the dump because of the failure of some 1 cent part that nobody could diagnose even if they wanted because they would have to reverse engineer half the board, rather than probe a few different points on the board?
Appliance repair use to be big business. Did it stop being so because washers and TVs and vacuums became too complicated to understand, or the parts went up in cost, or because $1000 is considered cheap enough of a device to be considered disposable? No. They stopped existing because appliances stopped coming with the reference materials to repair them in a reasonable time and parts are obfuscated from their source so people don't even know what their broken part is half the time. Is that a thermistor, a capacitor, a diode that blew up? Have fun spending the next 2 hours tracing the obfuscated part number down through 5 different suppliers to figure it out because you obviously can't test a broken part and there is no schematic to look at and identify it from.
Major appliance repair is very much still a thing, and manufacturers share repair info under their partner programs. But this makes sense because shipping them back for warranty is prohibitively expensive and people are willing to pay a few hundred bucks to fix a couple thousand dollar appliance. They’re still not doing component level repair, because module replacement is still cheaper and more reliable.
Small appliances and electronics are not repaired as any more much because:
1. their real price has cratered over the past 50 years
2. they have more integrated and specialized parts that simply aren’t repairable or available
3. They have fewer mechanical parts prone to regular failure or which pay the bills for repair shops (belts, timers, etc)
4. They are far more complicated than their predecessors, and therefore more complicated to diagnose even if you have a schematic
But yeah, when everyone’s washing machine has a belt transmission and a clunky mechanical timer, they failed all the time and there were repair shops on every corner. But these places weren’t doing the type of work akin to SMD rework on a digital circuits.
