I bought Google Wifi because I wanted a mesh wifi network and I expected their firmware to reasonably secure. Most of the major router companies have atrocious security records.

I think the more worrying aspect is that they probably deprecate it in a few years and you don't get any firmware updates any more.

Alternatively, do, and go in with eyes open on the fact it might collect data from you.

That and their support is terrible. I had a google wifi AP die 3 days outside of its 1 year hardware warranty and their support told me, nothing I could do but throw it in the trash. They don’t repair them and wouldn’t replace it for me. Google also doesn’t have a great track record of long term support for hardware devices. Although with Nest division that might be different.
