I didn’t bother reading much of your comment, but businesses obviously already need to detect which countries users come from. I’m sure you can come up with at least one reason on your own.

Yup. Just moving between German and French websites can be a pain in the ass. Default filters in shops, prices with or without taxes displayed first for professional things, different menus etc. They can be different in the most subtle ways, which is way worse imo.

Don’t get me started on websites who think they know better than you which website you’d like to visit. Stop redirecting me based on my IP or language settings! OK now I’m just venting sorry
