Ultimately, the Clause is not meant to transition an open source project with the intention of staying open, it's to keep as much openness as possible when events happen that force a project to close certain things.
I think a lot of the fear is that this will make a lot of open projects close up. This is not the case. Other things are forcing projects to close, and ignoring those forces and blaming it on evil investors and business people is not only disconnected from reality -- it's a really sad an un-empathetic view towards those that _actually_ develop this software (actually = git commit history).
