Yeah. Users who can stomach it should be sneaking back and pointing more refugees to Lemmy. Honestly it should be bots being like "If you like r/pics stay here BUT if you like r/pics and hate Reddit's policies? Try c/pics@lemmy.world" and just have the bot script for communities the fediverse has equivalents for. We're growing still but it's not like I'm seeing much Lemmy mentions in the discussion threads yet. That ship is sinking though.
I'm not saying that isn't happening but it must be happening selectively because the small niche subreddit I moderate still has the post up where I announced and linked to the Lemmy community I made. I just went to the subreddit in my browser while logged out to verify that it's not in the shadows, but I could see it.
Yeah, it should be obvious that you won't have much success using Reddit as a platform to direct users away from Reddit. They've made it pretty clear by now that they aren't free or open. Makes me wonder what other topics they've done this more subtlety for, or will do in the future.
If you want to direct people to Reddit alternatives, you'll probably have the most luck on platforms that aren't Reddit.
Though I do wonder if Twitter and the meta platforms will also block it, since they are competing with the fediverse as well (though meta in a EEE kinda sense, so they'd need to walk a finer line since they are supposed to be embracing right now).
