You can be in favor of improvements without blacking out entire communities. I’ll choose an imperfect product over no product. If Reddit removed the mods I’m sure others will line up to volunteer. Not even all mods were in agreement in other communities over the blackout. Mods can also resign if they feel they can’t do their job without the third party apps. Reddit claims 93 percent of moderation actions are taken on desktop.
The solution should be for Reddit to make such tools available themselves. Else the communities may deteriorate and and their hand will be forced as users make the decisions for themselves to leave.
