there needs to be like a mozillia vs chrome thing here no? What's the best try so far for something like letsencrypt or mozilla foundation for not owned by big tech email so "will consider a move to office365 or Google Workspace for their mail" the sender has this other awesome option?

If you wanted to operate a haven for independent email hosting, where you want to assure deliverability in the face of Gmail's sender reputation system, you would need to classify your outbound traffic, and have a death penalty for spammers. If you tolerate any activity that peers classify as spam, that would tank your reputation.
