I saw this exact popup yesterday, I remember seeing something similar to it before but it has been quite a while. The thing is, this single popup broke my computer entirely, I was playing a game and it jumped in front of the game, immediately stole the games inputs and I couldn't even pause it. Then clicking don't switch did absolutely nothing and the popup remained there, and any attempt to forcefully close the popup failed. Also, I was streaming at the time to my tv, and attempting to use any system related screen is blocked (and this popup counts as a system settings screen!), So it just crashed the entire thing while I was trying to dismiss or close it. I was stuck and couldn't even reboot, had to hold the button and lose any progress I had in the game.
So yeah, I would be very interested in not letting this happen again as well.
I can't say about all of them, but the RiF developer clarified it for the verge, taken from this link :
If RIF is still working for you when you’re logged out, here’s why.
“When users are logged out, the app is still working because it does not use the OAuth client credentials while logged out,” developer Andrew Shu tells The Verge in an email. However, he expects that the app will stop working in this way soon.
