It’s mostly the argument of a single guy (ljharb), who has very strong and weird opinions.
There were several extremely long and unproductive GitHub discussion with him posted to HN before, where he sent unsolicited and unwanted PRs to lots of projects that tanked performance by orders of magnitude and introduced tens of dependencies (he wrote himself), to ensure that projects would be backwards compatible with completely irrelevant targets they never supported in the first place (like Internet Explorer 1.3 under Windows 95 or something along those lines).
When projects did not want to take these contributions, he played his TC39 authority card, and when that did not help became more and more incoherent in his ramblings.
My take is that this guy actually wants to and thinks he is doing good, while actually having lost the plot a while ago.
