I do like to see it-- and I'm not with all these negative lemmings, a handful of people jumping on Reddit isn't a big deal since we're talking millions of users (and by the way it's healthier for Lemmy to not shun double dippers, not everyone's communities have migrated).
Also, having moonlit at a social media company, I can say shortsighted folks do jerk off to engagement metrics, usually traffic and interactions. Doesn't change a death spiral, and usually more experienced staff know to take it in context (I e. Is it lower than last time) so either you have dumb staff relaying bad information to the top or you have smart staff panicking, quiet quitting, etc.
In other words, folks need to relax. Reddit will do reddit things; just take comfort that you're not alone in the fuck spez mentality.
