Oh, not so though now, are you?
The moment every complexity imaginable were shoved into the web "because user experience", it became impossible to develop and maintain a competitive browser project by a non-profit company. More and more websites simply do not work correctly with FF, because companies don't give a shit anymore. "Just use Chrome". And if you install any anti-tracking software, they just break and you can't get any stuff done.
So now bend over and get used to Googlenet, where in just couple of years you're only going to be allowed to visit content "fact-checked" by Google's Ministry of Truth, and you need to sign an EULA that require you to wear an anal probe at all times when browsing the web, and half the screen is always an ad.
Good job everyone! You destroyed the WWW, and turned it into oppression tool, because what we needed was SPAs, dynamic content, 4 versions of CSS, 4 versions of HTML, and so on. Google & other corps embraced, extended and extinguished web and we were cheering.
