Imagine if compilers were only available via the SaaS model. Developers and the tech community in general would never accept this, and compilers were open sourced well before the internet had developed to the point where it would even be possible. Nobody would trust a system that sent their proprietary code off to a data center to be compiled to binaries for their platform on a monthly subscription model - the idea is ludicrous.
Currently the only SaaS product that still makes sense are LLMs, but this is temporary - anyone with sense realizes that the ideal situation is to run an open-source LLM model locally and privately, but this still requires a significant investment in high-end hardware and IT technical people.
That's the basic calculation: is it overall more efficient and less expensive to hire a skilled IT team to manage your in-house solutions, mostly open-source, including security patches, than it is to rely on external providers who charge high monthly fees and use all manner of sneaky tactics to keep you locked into their products? The latter is going to win in the long run.
