This is ungoogled chromium: https://github.com/Eloston/ungoogled-chromium
Two things to note from that thread:
From what I've read, Mozilla had some agreement with Google to keep all the data from their tracking stuff silo'ed so it wasn't aggregated with other data and wasn't used for anything besides showing back to Mozilla people.
and
They're now (and have been for more than a year) respecting DNT, removing the GA code so that you don't make any requests to google if you have that enabled.
As for Firefox including Pocket, they own Pocket for starters, and it's less annoying than Edge or Chrome pushing their analytics filled services. There's a lot less cruft on Firefox than in other browsers. If I really wanted I could use one of the GNU forks of Firefox, though I'm not sure how much more privacy conscious they may be aside from a bunch of brand rework.
And I also got burned by the very badly managed WebExtensions thing. I can totally see where GP is coming from.
