The point of the article is that the web ecosystem is breaking compatibility with “old” servers every six months or so these days.
First certbot broke. Now, older tls. Next, they’ll probably deprecate tls 1.2.
I imagine http 1 or 2 will be on the chopping block in the next few years.
They can’t kill both http 1 and http 2 because http 3 needs to use at least one of them as a signaling protocol to establish connections. I’m guessing that means there will be an http 4 that breaks with http 3, but doesn’t need a separate session establishment protocol. (Http 3 partially breaks TCP, and replaces it with userspace stuff. Http 4 would complete that process.)
The web was a success precisely because it was simple and stable enough to let everyone escape from the old hosting providers. They heavily censored content, charged high fees and so on.
Now, hosting is unnecessarily complicated, and the providers are consolidating back into a handful of players like facebook YouTube and cloudflare. Censorship and mass surveillance are on the rise. Since more people use computers than before, these players are helping kill the free press.
Telling people that operating a static web page should be a full time job, because it’s (been made) really hard is just accelerating these trends.
