I _don't_ think it was just ego. I think it was a smart strategy because formal standardization tends to bring in complexity, and just letting folks go off on their own and document their own usage (or "flavors") ends up being Good Enough in actual practice. It sucks from a standpoint of what I personally find satisfying, to be clear. But based on what I've seen over the last 20+ years, it is the strategy that is much less likely to yield a format that gets captured by giant companies that own a hyper-corporate standardization process that eventually gets enshittified.
Thanks for responding, Anil! Like I said, I really liked the article overall.
I don't agree that the Standard Markdown effort, had it succeeded as originally laid out, would've resulted in "hyper-corporate standardization". I mean, one of the main actors was Jeff Atwood, just about the least "hyper-corporate" guy there is. And I also don't really see any possible trajectory for Markdown to get "enshittified": after all, for the most part it's just plaintext with formatting conventions that existed way before it. Even if some corporate entity had somehow badly messed it up, markdown.pl and the other pre-existing implementations would have continued to exist.
