It’s also a volume thing. By the time I reach a reddit comment thread what I wanted to say has already been said, and if I say it again my comment will drown in a sea of heavily upvoted comments. On lemmy you can be several days late to the party and still get both upvotes and responses.
Pretty sure it’s always been upfront with that it still tracks you? I always thought of it as a “don’t store history and cookies locally” thing and nothing more. Maybe I read that disclaimer with more cynicism than most?
