People at Mozilla care so much about privacy, to the point that (when I worked there 2010-2012), they refused to do "services" the same way Google did (aka a login and a central server). So as a result, Chrome "just worked" and Firefox was completely unusable.
The people at Mozilla really care about privacy. But they also have to build something people can actually use. That means finding a balance between privacy and usability.
To you it's "fixing the Internet", but to most normal people it's "removing features." Like, can you imagine explaining to the average user why they can't just type a search into the address bar and get Google results?
(More specifically, though, what would you strip? Pocket is owned by Mozilla and is just a fancy bookmark manager, but sure. Google is just a default search; data isn't being sent to them. Outside of those, what would you remove?)
