I hate it too. Not only languages change, but many other things like date formatting, mathematical formatting (using commas rather than dots breaks few things around) and currencies too! And it's a pain to fix as settings often collide and with many applications abusing microfrontends you can even end up in conflicts on the very same pages. Google's the worst offender on all of its services and not just search, youtube, etc (even for work, their forced localization breaks Google Sheets in multiple ways), even my goddamn portoflio prices get converted in the local currency or using google flights shows me prices in the local currency forcing me to open more tabs to convert non stop. And changing it to my own, on so many different services is such a pain. But I know why this happens as a developer who advocated multiple times with my managers to not forcefully try to compute the language/region/market of users without giving them a simple button flag to change locale: product people don't listen and would rather have thousands of "ifs" that eventually will fail rather than listen to reason. Hell, as a developer I have all my software and preferred language to english, even though I'm italian. And sometimes I use VPNs! Even Amazon at times gives me some text in a language, and some other in others (completely unrelated like German) on the very same page. Just keep it simple.
