Eh, there are a lot of people here who don't use most or any of those services as it is. And there are far more "American Tech" products you all use out there that you're probably unaware of, and many things you think ARE American tech are actually Chinese or other country's tech, so I don't know why not just frame it as not giving money to tech companies broadly and just shutting off social media like you should anyway.
This framing leaves you open to just move your money from one branch of the same oligarchy to another while thinking you're making a difference.
