I don't understand why Mozilla is trying to control the ecosystem. It's an open source product. Why does it need to be locked down like this? Who do they think they are protecting, or even helping, with this?

Their users?

I'm not sure what you're asking. It's trivial to remove the block for open source contributors, and in fact Iceweasel etc likely won't have it.

But for people who download Windows binaries (or get automatically updated) it's a godsend.
