This is interesting as when the subject of setting up your own server comes up, people always complain how much of a hassle it is to maintain sender reputation with Gmail and Outlook. This leads me to two thoughts/questions: 1. Maybe successful decentralization schemes should be made providing for some peers that will be private for-profit? I know that (for example) IPFS encourages building services. 2. What could we do to ensure that small private peers will continue to be viable, even if some large for-profit peers will dominate? Of course such measures should be reasonably resistant to being used by bad spammy/illegal actors etc. ("Bad actors being bad" is always a handy rhetoric for overcentralization, but the problem itself should be obviously addressed.)
