I checked the wiki page of those vessels and it seems that the majoity they attacked was affiliated with Israel. One example was one Norwegian ship that initially claimed no connection and later turned out to have made a deal to deliver to Israel in January (the attack was in December).

I would say, if they are putting economic pressure on Israel as a means of sanctioning them, I don’t see the problem. Better than all the other counties that signed documents that forbid them from supporting a genocide but have not sanctioned Israel.
