My preferred way to browse here is using All and blocking communities I don't want to see. That way I get exposed to new things I wouldn't seek out on my own (for example: British archaeology)
I accidentally blocked a community while trying to block a user and when I went to unblock it, I saw I had 1250 communities filtered. If I had to guess, 90% are either porn, sports, or anime.
The 'them' in your first comment was pretty obviously about the lemmy admins on those servers profiting from doom scrolling. Now you are talking about "news" sites selling your data.
This sounds like something you made up to not be wrong. It is ok to be wrong. Just incorporate the new info and move on.
Or you guys just misunderstood each other. It is ok to misunderstand each other once in a while. No one needs to be declare right or wrong for this interaction.
