Yep, that's what it always is. Strange as it is to say, maybe we need to be a bit more tolerant of spam, after all it's never going to go away, it still happens on corporate enshittified platforms (so consolidation doesn't really help). Maybe we just need to get used to it and not give up what's important over being mildly or moderately annoyed. Just delete it and move on with your day. You'll still deal with it on corporate platforms just the same, so why sacrifice freedom for the cost of being slightly less annoyed. Ads in the inbox are so much more annoying than spam which can be deleted and blocked, that's the trade off.
