I totally agree with you. Moreover, I would say the same about different email addresses under a single domain of a big email provider: Donald.Knuth(at)gmail.com and BuyThisNow(at)gmail.com belong to completely independent entities and should not share reputation. However, we live in an imperfect world, and if some email provider would declare themselves "big" but offer unlimited number of free email addresses for spammers - then everyone else will likely just block the whole domain. Same with free domains heavily used by spammers. Actually, it was on this list where I saw freenom (the company offering free .tk domains) being praised for fighting with spam, for the first time. Critical difference between PSL and anti-spam is that example.org being on PSL and protecting sub1.example.org from cross-site attacks sub2.example.org won't hurt the rest of the world who might be unaware of this corner of Internet. However them not sharing spam-reputation might mean that after spammers used up all reputation of all subdomains from sub1 to sub1024 they can just hop onto sub1025 and start sending spam to rest of Internet from a clean domain with no negative reputation. That's not what the rest of Internet wants. Saying that, I agree that idea of damaging reputation of all *.eu.org subdomains including yours is not ideal, but sadly it looks like big part of antispam community considers "good enough".
