I don’t mind algorithm feeds as long as it’s not the default view and as long as it’s not mingled with the normal feed. Reddit is an example of the latter case. They mix “promoted” content as well as “you visited a subreddit once so we think you’ll like this post” content along with posts from subreddits you subscribe to. I find that annoying.
So I wouldn’t mind if Lemmy had an algorithm to recommend posts as long as it was in a “recommended posts” section. Then people who want it could click over to it and people who don’t like that could just ignore it.
It definitely has shades of the anti-vax idiots that said they'd rather have their child dead of a preventable disease than to have autism. As a parent of a child who has autism, the parent of a neurotypical child, and a person who is autistic, I'm happy that all three of us are alive and well and disease free thanks to vaccines. Even if vaccines caused autism (which they absolutely don't), I'd rather my child be autistic and alive than not autistic and dead.
