The difference isn’t nil, but the point is that these institutions can be quite effective.
I’ve reported issues to the DPA (Data Protection Agency) of Belgium and they handled it reasonably well, which I didn’t expect either.
Marketing tactics are part of consumer issues and many countries seem to have good consumer protection laws. Of course Grammarly’s issue was towards/against a business, and that colours the problem. I think the damage to their reputation is enough punishment, but there might be other ways to tackle this.
I merely fail to see the point of “oh well, the Humanity, what can we do”. Apathy is death.
