Will they though? I don't think they will for 2 reasons:
1. Ad blocking on Safari has worked like this for years and none of the major ad networks have chosen to act on that fact.
2. It has always been possible for ads to work around UBO in various ways but no major ad network has even tried (e.g. server-side embedding of randomly obfuscated JS).
Ad blocking on safari is obscure, I regularly see tech threads where people aren’t even aware it exists. Mobile ads blocking for default browsers was always a puzzle. This means too little market share to address.

Cause arms race with a dynamic blocker is expensive and futile. You are trying to s/UBO/UBO Lite/ in this sentence and convince things will work the same way, they won’t.
