Optional yes, but before it can be offered it must be in privacy policy. And there we have another questionmark — where is the data stored and by who.
I enabled it, thought. Mainly because I’m not a company or a community as EU sees that, and then GDPR etc doesn’t apply directly. But even then saving data itself is regulated. If it is saved by one of those big ones, then there isn’t any bigger issue [1].
hate to say this at loud, but potential issues by government of US are still there ↩︎
