Because HN's development prioritized "good for the user" over "good for browser developers". https://www.w3.org/TR/design-principles/#priority-of-constit... https://datatracker.ietf.org/doc/html/rfc8890
Anyway, the "errors" that OP mentions are simply just deprecated attribute styling and like, one or two instances of center tags. Hardly breaking anybody's back to continue supporting those.
Apparently not “good for the user”, given how many people here have commented about the increased font size or custom CSS extensions they need to use on HN to make it readable.
