If the goal was to "trigger" him I don't think the protests succeed in any meaningful way. Innocent Tesla owner where the primary victims followed by share holder, (damaged) property owners and people affected by insurances premiums due to the vandalism.

And then of course there are still a handful of people in jail for crimes committed in relation to the Tesla protest. Arguably not victims but still a negative effects that clear outweigh any perceived positive effect it all had on Musk.
