I personally am most worried about Facebook's attitude toward dissent on this issue. There's clearly an overwhelming number of developers who want Facebook to simply adopt an established open source license, preferably just BSD, with no extra conditions. The fact that Facebook has continued to ignore this sentiment tells me that it's no longer a place where developers have much influence. I personally don't want to contribute to or use open source software from such an entity. But that's just my personal opinion. It's a shame, because I've been really impressed and happy with the work Facebook has done in the area of programming languages (Flow, Hack, HHVM, etc.).
