They’re not really debloatable but you can use alternatives. Newpipe can handle YouTube. Invidious instances in the browser. Something like libredirect can send you to alternate front ends for Reddit.

can’t access the GIFs panel without internet access…just standard emoji…I don’t use those anyway so can deal with that.

Yes probably. It’s a compromise and not ideal. I revoke internet access and on Graphene OS not tied to a Google account. We all find our own peace with this kind of thing. Florisboard looked very promising but the swipe text wasn’t implemented last I checked.

Unfortunately Gboard is still the best around. Block it’s internet access.
