> Google's sessions do not expire, so that more user data can be collected. That is clearly more valuable to them, than compromised accounts due to session hijacking. Them doing it, is not a great use case for others, because their value proposition is entirely different than for most other web applications.

I think this is a pretty bad take. Google runs some very sensitive applications for paying enterprise customers, and they still tend to not expire sessions.

I also really don't like Google as an ad company, and I think my trust in their judgement has fallen precipitously over the last decade, but I find it hard to compare them to someone like Microsoft and say they're doing worse on the security front (I don't think they are).
