Don't forget the difference between "free software" and "open source". Open source was, from day one, pushed as a tool of capitalism: big companies could make more money if they collaborated on common code with each other. The free software movement (whence the GPL) always operated on the idea that, in an ideal world, software wouldn't be copyrighted at all and everyone would just publish their source because that was the right thing to do. The open source movement (whence the MPL) merely argued that open source was the profitable thing to do.
A lot of companies embracing open source have succeeded in building an OSS utopia for themselves internally, and selling software as a service to other people. There's an unprecedented number of people employed by big companies working on things that are nominally free software, but it's free software to do things like large-scale container management, not photo editing. (The free software folks, to be fair, did see this happening and responded with the AGPL, but that strategy seems to have had about zero effect.)
And even Photoshop has realized that switching to a billing model that more closely resembles SaaS than traditional proprietary software is more profitable. But a better comparison is something like Thunderbird vs. Outlook or LibreOffice vs. MS Office: those fights have ended up with both participants losing out to Gmail/Outlook 365/etc. and Google Docs/Office 365/etc., which are free-of-charge, high-quality, and even more non-free than proprietary software that in theory at least you could disassemble.
