Some of them provide utility and some don't, which is why we don't allow children to drink, smoke, or gamble. If a company providing those goods and services targets those demographics it gets political action.
Welcome to the nuance of society and the modern world.
But they're not disallowing children smoking, drinking, or gambling here. It's more akin to disallowing children from drinking Smirnoff, smoking Marlboros, or playing blackjack and nothing else.
Even equating the arm of a militaristic expansionist dictatorship to a tech giant is disingenuous to its core, Google collects a shit ton of data but even that pales in comparison to TikTok's absurd collection. But all of that aside, your argument is shit. Reign in every tech giant at once? Why? Why the hell is it all or none? I don't even think the US Federal Government in its current state has enough authority to try that, at this point.
That's like choosing not to take a doctor's license away unless you can take away every bad doctor's license in the USA at one time.
How do you suddenly go from comparing these platforms to alcohol and gambling, saying they have no actual utility, and saying 'every little bit helps' when it comes to regulation to asking why these companies actions should even be regulated and why the law should apply to them all equally, even going as far as comparing them to the role doctors play in society?
That's honestly one of the most abrupt 180-degree spins I've ever seen.
