It’s not a controversial viewpoint that a child can’t consent to their information being uploaded permanently to the internet, even by a parent. This is because, as an adult, I can’t retroactively remove my presence from the internet. Seems silly in trivial cases (school website), but is quite severe in others (bathtub photos).
It’s also not controversial to paint the harmful, profit-seeking actions of companies upon minors as “abusive” (e.g. tobacco firms).
If anything, your knee-jerk response at their rhetoric raises eyebrows: why would you go to bat for a company who by nearly all public measures is fundamentally evil in aim and structure?
If there's something wrong with how we've organized our society than we need to fix it on a societal level.
Evoking what the comment in question evokes over uploading pictures of your kid to the internet is not the way to convince people. It takes the thing you want people to care about and exaggerates it in a way that makes your view point trivial to dismiss.
I say this from the place of someone who deactivated their social media accounts over similar concerns. This is not the way to convince people.
