Google collects plenty of personal data and they might want Chrome data, but it's one of those lines it doesn't make sense to cross. At least in my opinion.
Drifting into the generic concepts presented in many of the Google threads, it seems a lot of people complain about reductions in SERPs and conversions. There isn't much doubt the internet is continuing to change.
Today, I happened across a regionally focused site that appears to be monetizing with AdSense and cross promoting other sites they own. Meanwhile, I've been establishing well curated information in different regions similar to what they provide. I suspect I will eat their lunch.
I didn't hunt them down or target them, they just happened to be focusing on an area that I'm currently looking at in a bit more depth.
I believe every page I control runs that same risk. There's someone coming along who's going to bring some significant focused energy to that page's niche.
