How many important emails have been lost due to spam filters, how many important packets have been dropped by firewalls? Or, how much important email or important packets weren't sent because "it wasn't worth the hassle"? I'm sure all of that happened, but to which proportions? If it wasn't worth it, the measures would have been dropped. Same here: I regard it as a test, and if it isn't worth it, it'll be stopped. Personally, I run with a 'no spam' sticker on my physical postbox, as well as a 'no spam' for salesmen the former of which is enforced by national law.
FWIW, it is very funny to me, the people who ignore it: 1) very small businesses 2) shady businesses (possibly don't understanding the language?) 3) some charities who believe they're important (usually a nice response: 'oh, woops') 4) alt-right spammers who complain about the usual shit they find important (e.g. foreigners) 5) After 10 years I can report Jehova's have figured out the meaning of the texts (or remember to not bother here)!
It is my time, it is my door, my postbox. I'm the one who decide about it, not you.
Same here. It is their time, it is their project. They decide if you get to play along, and how. Their rules.
I think that’ll also happen to most open source projects that adopt a policy of silent auto-rejection of contributions without review.
