People have been doing that forever. Difference is, 30 years ago the homeowner would have just crumpled it up, thrown it in the trash and it would have been immediately forgotten. But now everything has to be put on social media for the whole world to consume and every one-off instance of someone being a dick is magnified into some huge commentary on society, requiring people express their shock or outrage, and then their shock and outrage at the subsequent backlash, and so on and so on.
I guess this is what passes for entertainment now that the big networks have stopped making good TV shows.
