I like the sentiment a lot but curious what law this is against that has prison time as a consequence? I can’t think of any, but if there are none, we should pass laws that allow this to put these people on notice and then aggressively prosecute.
Difficulty: it’s a wobbler, and is only a misdemeanor unless it’s > $400 worth of damage. Good luck proving that in this situation.
Maybe if they wrote in an email their evil plan to set the printers on fire so their customers would buy new ones, and it caught some people’s houses on fire.
Civil claims or a class action are an entirely different matter of course.
