The amount of time it took you to type this response is longer than it takes to enable third party sources in settings. Most people do it at some point anyway, such as when downloading an app they want from it's website. There's no mangle about it, it literally pops up with "allow this app to install applications?" and takes you there directly.

If someone wants f-droid they'll do it. The problem is most people don't know what f-droid is. It has nothing to do with UX friction of installing it, there is virtually none.
