Those were cheap tablets from Aldi / Medion one could buy in Germany back then and they required a mandatory Google account to use them. Can't remember their name; they cost about 150 Euros back then.
I found it unapologetic to get my account, which I then have used for years, cancelled without any explanation or sign of wrongdoing.
But what should I say. I didn't pay for it so it was well within Googles rights and discretion. At least this made me aware that such behaviour exists.
that was forced on some cheap androids between version 3 and 4.
after 4.4 they dialled it back to instead of required now they only apply some seven dark patterns to try to trick users into thinking it is mandatory.
same effect to most users, zero regulatory consequences
