I'm unconvinced that what they're collecting is personal information. The closest would probably be location, but that's very coarse and is based on user selection not IP (which isn't stored). I might be wrong though, what data were you thinking could be problematic?
I'm not a lawyer, but my understanding is that anything that identifies consumer or group of consumers falls under GDPR.
General Data Protection Regulation, it's not only about personal information, but what data is collected by companies, who has access to it and why/how is it processed.
I agree that they are not collecting personal information. They are collecting information about your computer system. According to the ICO definition of personal data, it means "any information relating to an identifiable person who can be directly or indirectly identified in particular by reference to an identifier."
