Holding up snarky signs doesn't seem to be working.
For me, it isn't about whether this action is appropriate or not. It's about how this kind of action is inevitable.
I'm going to let Dr. Martin Luther King Jr. explain in a quote no one seems to post during his annual holiday.
"It is not enough for me to stand before you tonight and condemn riots. It would be morally irresponsible for me to do that without, at the same time, condemning the contingent, intolerable conditions that exist in our society. These conditions are the things that cause individuals to feel that they have no other alternative than to engage in violent rebellions to get attention. And I must say tonight that a riot is the language of the unheard. And what is it America has failed to hear?"
If you only speak up about a supercharger catching fire and ignore the unheard, you are prioritizing a thing over people.
