Those institutional allocators are fiat maximalists and they don't run their own node and verify txs by themselves. They all go to CONBASE or someone else to custody their coins. Why do you think that they would ever care about spam? This whole issue mostly affects the self sovereign bitcoiners who run their own node. Do you form your opinion based on what institutional allocaters tell you or self sovereign bitcoiners tell you?
Moreover why do you think that pro-filters people think spam can be stopped? I have never seen any bitcoiner (who understand the spam and filter) saying that filters would stop the spam.
The goal has always been to mitigate spam not fixing it. There has been a lot of data proving the point that filters absolutely mitigate the spam. I can't believe that you are still making this argument after 2-3 years of spam war. Very disappointing.
Since you used to be system engineer, I assume you must have been a part of process where you had to mitigate the risk even if you knew that you can't completely fix/stop the risk.
With due all respect, the more responses I read from you the more I think you should seriously come out of simpfluencers & coretards circlejerk. You can still not support knots and I respect that but you should seriously consider researching more on this topic.
