In Memmy, go to the community, under the menu is an option to Block Community. It's kind of an endless game of whack-a-mole. My all feed has improved, but every day there's a few more I have to block. I like to check All occasionally to get of my bubble but it's a bit of a mess.
Not that Reddit's All feed is any good right now, which is at its absolute lowest quality I've seen in over a decade. Resembles instagram more than what used to be Reddit.
If this was the reason for OPs claims about the foundation I really would rather they elaborate rather than the rest of us guess what they're talking about.
What a spectacularly ironic post OP. You make an incredible claim while providing zero proof. Can you see how that makes you the asshole, talking shit about RPi foundation? On top of that you edited your post to call us all stupid for calling you out. Incredible.
