Noncompliance should be reported.

Everyone should just geo block EU visitors instead.

I know a lot of people that wouldn't mind that.

1. There are ways to bypass geo-block.

2. People would build alternatives specifically for EU (with few exceptions).

3. They could even offer those alternatives to US, but with better privacy out of the box.

Yeah, fuck everybody else's privacy. /s Why are you like this?

majority of sites don't have a clear "reject/decline all" button. I think they deliberately make it complicated.

On #1, yeah, you can. But don't expect the site to respect the EU laws.

I'm all for the hostile corporation to hostilize themselves into complete inaccessibility too. Let them build their castle, with a moat, and not let anyone near them. But unfortunately, they are still smarter than that.

(But anyway, they seem to be getting dumber by the minute, so there's still hope.)
