Google has always been really weird with accounts. Back when they were still pushing Google+, I could not register with my Google Apps account because it didn't end in @gmail.com lol. I have a permanently grandfathered free plan, but if I were paying for it and I cared about Google+, I would have been pissed.
I concur. I just moved away from Nest because they stopped supporting accounts that don’t end in gmail.com. It’s pure madness. I’ll never buy another Google hardware device again.
