That's only your opinion, and completely detached from reality. I know few people who, for one reason or another, did not participate.
I never saw a single post complaining about participation event. Grinding events, or as some call them "collecting events", increase amount of old, boring, grinding decks in arena. They prevent people playing for fun from having fun. Even if I wouldn't participate (as in care about number of collected items) I would still had to face one grinding deck after another. The only way to "opt out" is not to play. How event forcing players to not play is supposed to promote game? Fail troll is fail.
Participation - yes. Grinding, errr, collecting - no.
