The whole purpose of F-Droid is to provide an alternative to the Play Store for people who don't want to or can't install Google's proprietary code. Anyone who has play-services installed would just get Mozilla's official Firefox releases from the Play Store and not bother with F-Droid. They're removing support for that non-free library because their user base is people who've already decided they don't want to use it.
