@JMYGI The problem, as I see it, is much wider. Recent years ST, instead of supporting community open-source software, selects/builds proprietary closed-source technologies which lock customers into ST's solutions like ThreadX, TouchGFX, and now NemaGFX. It is a bright red flag. Even from mcuboot ST had to create own customized SBSFU solution.
Ofc, ST is for-profit company and it has to select the best strategy primarily to please the stakeholders, rather than engineers, but when such strategies are too aggressive clients simply go somewhere else. Especially because the whole software industry is more mature than it was 20yrs ago while, in my opinion, ST makes similar mistakes Microsoft made during Steve Ballmer era.
