I get the whole privacy thing to do is to move to signal or telegram or whatever but all my friends have been using discord (or steam for a select few) for so long that trying to move over to something like that would take too much effort than I am willing to give.
Is discord (or any other major site for that matter) a data harvester? Sure but at this point I could care less. I use fedi because I just much prefer it over birdsite or bsky.
