It belonged to the British East India Company, a government-backed trading corporation. A private corporation with government-backed power that was granted monopolistic power over Americans via The Tea Act of 1773. Colonists targeted the tea, not the privately owned American vessels. Collateral damage was specifically avoided. John Andrews wrote that the group responsible swept the decks and replaced a broken padlock. It was a symbolic act against the British, not wanton destruction of property. Tesla isn't a monopolistic entity foisting systemic injustice and oppressive colonial policy upon Americans.
I understand the spirit of your argument but it's a stretch for me. The Boston Tea Party was about rejecting external control. In this case, what policy is under protest? Is it Elon Musk himself, Donald Trump, capitalism, the election, or tech culture? The destruction we are witnessing is haphazard. What's the shared goal?
