> Outlook.com and similar are an anathema to email. This is why they tell you not to run a mail server .
It turns out that whoever has the most power is the most powerful. This is why distributed/decentralized systems cannot singlehandedly free us from tyranny, and why I find people who spend all their time preaching decentralized systems to be quite silly. We don't need better systems (well maybe we do but,,,), we need better education and awareness of how billionaires manipulate us; this goes beyond software.
Decentralization is not a bulletproof solution. It is a mitigation. Until someone gets 50 percent of market share. Then they can run havoc on the ecosystem with their own customized system.
Complain all you want about the monopolists, and I do think you're right to do so, but a lot of their power comes from and is aimed at defeating the overwhelming flood of spam.
Mail, then emails, then home phones, then cell phones, then texts, then social media have been gradually rendered less and less usable by bad actors systematically abusing every single tool we try to use to communicate with one another to steal from us, lie to us, and manipulate our beliefs, and we'll just keep inventing and discarding new ways of communicating until we reckon with this.
