i've opened multiple, detailed support tickets over the years about different UX wtfs they rolled out that removed vital functionality.
not one of my complaints has ever been addressed. my last complaint was ghosted after i pointed out that they should actually read my lengthy analysis instead of giving a worthless canned response.
> no, but i author and maintain some pretty popular projects and now work for a company that does pay, and also has a massive github and OSS footprint.
Would you say that you (and your projects) and employer are to some degree locked in now? Are either you or your employer likely to move away from hosting your projects on GitHub?
my employer uses a lot of paid github features, while my projects use none, so moving away would be simple for me, but difficult for them.
the real lock-in is no different than any other social media platform: network effects. most people who follow you on X rarely bother also having an account on Y. unless you're Taylor Swift, moving away means diminished visibility/reach, and dilution of any reputation accumulated e.g. over a decade of activity, interactions, etc.
