(consumerrights.wiki)
This is a most excellent place for technology news and articles.
I haven't read the entire XDA thread but there are a few posts saying it's limited to ColorOS (Chinese version of android that everyone else gets as OxygenOS). Unable to verify.
If they don't reverse course, I'm sure it'll roll out globally eventually. This has to run afoul of EU's strong warranty laws right?
