You realize the web started with just HTML at first right?
The web was always meant to be a platform anyone could easily build on, whether they were experts or someone's little old grandma who barely knew what a keyboard was.
Not only is it gatekeeping, it's historically wrong and betrays a flawed understanding of the platform. The web has always been about ease of use and there have always been people who went out of their way to teach others how to make good use of it.
Yes, the web is broken, but the web is broken because it's no longer about everyone running a little shoebox of a server and instead now we depend on giants who see us as cattle.
