I'm going to concur that this is a grasping conspiracy theory without proof or evidence. You are phrasing it as a motivation of an offensive attack to try to sabotage others. That would be contrary to Tesla's mission statement. But I will put forth a counter theory that it could be a defensive motive. When Tesla wants to build a station, maybe they would "go big" in the initial build to get a large chunk of supply capacity. Because if others come in and build later, consuming more supply, then Tesla might be empty handed and out of luck if they want to expand that site in another 5 or 10 years. So better to overbuild some initially.Not sure if someone mentioned this but tesla is strategically maxing out the power company so it's extremely not cost efficient for a competitor to put chargers in nearby
So it may not be about trying to block others, but to get enough so that you don't get blocked later.
