Since I don’t feel like building things on Twitter anyway the old issue don’t bother me much but of course if I built stuff on Fabric and they yanked that I would be pissed. However I think the world has evolved this time around. Notice a conversation I had with the CTO of Twitter:

Of course time will tell and my guess is many more folks will build on these frameworks than were interested in building Twitter clients which means it could impact a lot more apps and ecosystems.
Interesting times.
