Yes, the internet is broken and badly designed. Because no one designed it, not in its current form. It's a patchwork of barely-compatible technologies being held together by a collective delusion.

On one hand, though, this is your most reasonable argument of all of them: security shouldn't fall on you as the last line of defense. Ironically, though, it most undermines your overall point, because the reason browsers continue updating is specifically to remove more security responsibilities from you. Since the attack surfaces continue changing, the security assertions have to continue changing too.

Sure, those three sites you go to every day are safe and trustworthy right now, and the network you access them from is uncompromised right now, but Microsoft had a supply chain attack just a couple of months ago. It's very possible that those trustworthy sites might be compromised tomorrow, and if you're still running an old browser with a known exploit, they could successfully target you.

But hey, you say, I'm pretty savvy. I'm not going to click anything stupid, or allow anything to download that I don't expect. Well, first of all, they updated the browser to ask you before downloading anything (they just did it a long time ago). But more importantly, what about a kid who is browsing the Web for the first time today? If they see a link offering them free Robux or whatever, they're not going to recognize it as sketchy. So they need those improved malware protections.

Remember, half of the people in the world are dumber than average.

You are demonstrably wrong with literally every damn post here so I’m just going to assume you are mentally ill and move on.
