It being free and open is exactly why the big providers are coming up with ever more "standards" that are complex to configure as well as "reputation" scores that are hard for small senders to clear.

DMARC is not hard.

"Reputation scores" and blacklists / greylists started in late 1990s / early 2000s as multiple grassroots efforts when spam started to overwhelm systems. Gmail did not exist, outlook.com did not exist, it was easy and expected to run your own SMTP (which I did). And it was very unpleasant.

DMARC appeared 10 if not 15 years ago. There's no reason for a sane MTA configuration not to have it.

Outlook.com is a rebranding of Hotmail.com which absolutely did exist in the 90’s.

Indeed, Hotmail was sold to MS in 1997, which I incorrectly remembered to have happened past 2000.

Microsoft has provided free email addresses to the public for decades.
