> the fact that I can get TeamViewer for free and use it to get remote access others' computers makes it feel like a higher threat attack vector for me.

I agree. I gave that example because I personally use it, but would prefer to move to a self-hosted or inexpensive paid solution. I've always assumed the free version has sufficient business value as a lead-generator for the enterprise version, but there's no reason to assume they don't also monetize usage data.

> I already had android, chrome, project Fi, and Google's DNS ... whatever marginal gain they get from having software on my router is negligible.

That's a totally fair way of looking at it, and I'd probably use Google Wifi with little hesitation if I were you. But this isn't the case for everyone. IMHO tech folks need to be mindful of privacy implications when recommending tech to non-tech folks, because we have the benefit of understanding those implications. FWIW, my immediate family would be displeased if I installed a Google router for them and they later figured out Google's conflict of interest for themselves.
