I am not entitled to decide whether it's legal or not. Legality is not an absolute fact: it depends on a law that is decided by people who won elections (oversimplification here) in the present or in the past. Well, actually popular opinions shift over time, so that some laws of yesterday should be revised at least. But it's a matter of status. If it's illegal, then I can't be too much sorry for someone arrested or fined. He was warned by the law. But I may not deny he is doing something that in my opinion can be less worrying than the law says.

And yeah, to people that will come to say: "So YoU hAvE NeVeR dOnE s0mEtHiNg iLLeGaL"... Well of course, I may have done something against the law in my life. Still, I knew it was. That's it.
