Typical dark pattern, very easy to accidently opt in, impossible to opt out. You have to call, and as you might imagine, could not get through.

It also doesn't help that the opt-in was not done by me, but by the builder, who set the ecobees up in that manner (new build). It's part of the "energy efficiency" that they offered.

EDIT: So I did some digging, and it's confusing to say the least. In the app, it points you to the Google store page when you tap more info about the program. A search points to a page that tells you to contact your hydro company. On my hydro company's page, there is ZERO information about this, then a second search that landed me on Google Support page, which finally mentions the program is administered by some company in the US that is "partnered" with my hydro company, hidden deep inside the terms and conditions. And on that page, it says I actually have to call Google to unsubscribe.

I've had zero luck with this ever. They're quite friendly at the Googleplex though and capable of redirecting your request wherever it needs to go.
