"... ~100% of all yahoo users were fake."
I also experienced the same problem as the OP when logging in today, despite having registered with a yahoo.com email some time ago.
It eventually let me log in this evening so I am guessing you have done something to remedy the problem.
Can confirm. I was one of the people who posted in the above mentioned threads.
I've just upgraded from a Milhouse build to LibreELEC 7.0.0 and the problem is back again. Same as before, Kodi can be seen registering a "Hat" and this is why each button press is registered twice. Kodi on Ubuntu registers 0 hats for the exact same controller and works fine.

Switched to Milhouse build #0515 and the controller is working fine again.
