Another example is putting country specific assumptions into your address fields, eg. Requiring a province in a from using a select, and offering only Canadian provinces.
Even if they support everything else, that quirk prevents you from shopping there without a Canadian billing address.
If anything was realised, it was probably that companies who decided it wasn’t worth complying weren’t really missed. The only encounters I’ve had with this myself are dodgy American news sites, and the “you’re blocked” page is essentially just a message that says “we can’t really be bothered following pretty basic practices” so… no real loss!
For this reason alone I despise the EU and the whole GDPR garbage. Apart from annoying you with cookie banners on virtually every website, so that you have to install a browser extension just to get rid of them, it has effectively caused significant parts of the internet to become inaccessible for EU citizens.
I don't blame GDPR for those pop-ups. I blame sleezy business models. Those businesses don't need to make those pop-ups so annoying, they are doing it on purpose. After awhile you'll recognize them and automatically open them in private/incognito mode
The only parts of the internet I haven't been able to access from the EU are US local and regional news sites who throw a 451 error because they are managed by immature people. If it bums you out that much, just check the page via archive.org. You'll see you're not missing much
