At this stage, it helps when more devs are motivated to switch over and build/improve stuff to cover the things they want to do with a phone. And there's relatively many devs among those who use F-Droid.

I'm not technically affected by Google doing l this just yet, because I don't use the Play Services, but with that move coming after they encroached on Custom ROMs twice, I can tell that I need an exit plan. And there's nothing quite for motivation than slowly being backed into a corner.
