I don’t know what everyone else thinks, but for me, GitHub is a shining star among most developer tools and services. Free hosting for code, sites, personal projects, no obligation to make your repositories public or buy a subscription. For most devs, they would never need to buy a subscription. Heck, I don’t need it, but I pay for it as a thank you for what I get (have gotten) out of it.
I am honestly shocked that they managed to survive and thrive after getting bought by MS! So please pardon my ignorance when I say that I don’t understand why some FOSS projects want to move away.
