Were I in that position, I would resist, just as much as if they were trying to put video cameras in my bathroom and bedroom.

I would suggest alternatives, and offer to research, order, and install them.

I would appeal to my parents' empathy, try to educate them on the risks these corporate-controlled hackable devices bring with them, and on the negative impact that surveillance has on human development. I would look for allies to help: siblings, extended family members, school authorities, counselors... anyone whose views they might respect, both alone and in groups. I would try to persuade them, and if it came down to it, I would fight.

If they stubbornly insisted, I would continue to bring it up regularly, both in private and in public. I would make sure that it was a constant drain on their time, and make sure they knew it was a constant source of resentment. I would escalate it to the point that they would have to justify it not only to themselves, but to the communities around us. I would consult social workers and government watchdog agencies for child/youth home environments, and find out from them whether my parents were breaking any relevant guidelines or laws.

And, if I somehow couldn't keep it out of my space or unpowered, I would open it up and disconnect the microphone, or perhaps wire a physical switch to allow connecting it only when needed. (By the way, reed switches exist that can be concealed within a device and activated from the outside with a magnet.) If I didn't know how to disassemble electronics or solder, then I would learn.

And then I would continue to fight.
