If Trump gets back into office, it’s game over, unless the people are willing to fight a civil war to stop him. Though even that will probably be too little too late because of the power vacuum it will likely create on the world stage when WWIII already looks possible in the next decade.
It might already be too late because I agree that Biden pushing his weight around with these new lack of presidential limits would get messy. But the cat is out of the bag right now and it’s not going to go quietly back in.
It wouldn’t surprise me if the way it determines how busy places are would be considered a bigger privacy violation than these webcams (which only show people in their areas while Google somehow can report on how busy many arbitrary locations are vs their usual).
