I still have no clue as to whether I should enable or disable Thread on my eero router.

To be fair, I use my main google account and haven’t had any issues in over two years now. But I also use SmartTubeNext regularly, so I understand.

Probably not, but I don’t really use google services. My account is mostly empty.

Same. It’s like $5 for 6 months if you use a VPN at checkout. At that price point, why not.
