At one point I said that CSS and JS are getting so-called "minified" (aka, make them pretend to be less bloated by moving the entire bloat to 1 line that lags in every single text editor), but not HTML.
Clown world surprised me once again, as it turned out I was wrong.

1. Go to weblio.jp (recommended to have uMatrix and/or uBlock Origin enabled and Javascript disabled, because trackers).
2. Look up any word you want.
3. View page soyce.

For example: https://www.weblio.jp/content/%E3%83%96%E3%83%AD%E3%83%83%E3%82%AF%E7%B5%8C%E6%B8%88

The entire HTML is """minified""" to 1 line.
This fucking cancer of a malpractice seriously needs to stop!
