Mitigation is required, if you actually do have something to hide.
Freedom however is endangered, if you personally mitigate this or not. I think for most people the best course of action would be to speak out against this, boycott the companies or get politically active, educate others about the threat to all of us.
And evading hostile tech's reach is really not a practical every day thing. I mean look at the shitshow of browser fingerprinting. Behaving vastly different than most will leave a trace of its own, even if it's just the absence of common information.
The best personal protection is being part of a healthy, democracy valuing collective not okay with this surveillance.
And if you are about to explode the next big story, I would probably advice migrating somewhere hostile to the country you are about to piss off. It's not like they turn on your fridge because you bought LSD for you and your boyfriend; I mean generally buying drugs happens in public Telegram groups these days... Politicians love spending money on surveillance tech, but not law enforcement people. Nothing is gonna happen, if you don't mess with powerful people's egos.
The real damage of these trends is the self censorship and permanent premptive self-surveillance you automatically do in the face of it. Like treating every device as hostile! You are killing off the mental freedom more and more, creativity, possibilities. No one is going all to prison, but no one isn't in prison a little bit.
