Once upon a time not long ago, I got off from my flight into a foreign country (I don't have a SIM card that would work there). I turned on my wifi and was delighted to see they had a public network you can use. There was a captive portal, and the only sign in options (besides using a local phone number) were Facebook and Google. I chose Google, and entered my id and password. Google promptly went into the "sus" mode as you described.
Now I can't use option 1 or 2 because I don't have internet access until Google approves my sign in. I can't use option 3 because I don't have a SIM card that would work locally. Thankfully Facebook login worked.
That's when you turn on the DNS tunnel (https://news.ycombinator.com/item?id=7619259 ). If they somehow detect that and try to block, change your MAC and repeat. Those bastards deserve it for trying to force users into megacorps' services.
Wow that's something devious!
