I see part of my work in freeware and open source as supporting developers even if I don't agree with them and there are a lot of developers on Github who have no intention of leaving. As a result, I feel stuck between an option where I see gloom and doom on the horizon and my own gut feelings about our site's mission.
That said, there's nothing really compelling me to use it. Back when Github first appeared, I stopped posting feature requests, bug reports, and wishlists here on PFW and elsewhere just because it just seemed smarter and more convenient to have it all in one place, monitored and easily referenced. However, part of the benefit of this acquisition is learning just how wanting Github is in a lot of places outside it's excellent usability. It's not unlike my journey away from Google's excellent services ever since I learned about surveillance capitalism.
Since they aren't the only game in town on this, I'll just start using other resources whenever I can. Plus, there are a thousand different software projects that need help and it's easy for me to give more of my time towards non-Github projects.
