Man, i hate it.
Not only a lot of communities are hidden because of Discord (at least with Reddit they were more discoverable), the worst part is the fact that they are unsearchable or behind a paywall.
Like the "join my discord if you pay at least 3$/mo!" is pretty innocent but you are gatekeeping a community that before was pubblic.
If we are talking about something like a content creator focused about an hobby or pc problems you can see how Google will become even more useless.
Reddit was the least bad choice between it and Discord but has failed the "i want to be a social network".
