>Not for developers or customers.

I am both of the above and F-Droid works just fine for me. Feel free to let me know how it doesn't in your opinion work for me if you really want to talk for others.

I think there's a difficult, fine line to walk here. For the average, unsophisticated user, requiring them to jump through hoops and enable scary-sounding options in order to install any random software they find off the internet is probably a good thing. But it does mean that for software that's safe, it's hard(impossible?) for developers to give a potential customer a good install experience outside the Play Store.

I think probably the solution to that would be for Google to allow developers to list alternative app stores on the Play Store. Maybe that should require a strong review process that involves actual humans getting to know each other, and extra fees to cover it, I don't know. But a company large enough to have a need for their own app store should have the resources for that. That might leave out groups like F-Droid, though, so hopefully there'd be a way to get them in there too.
