If I follow your logic, you seem to be saying: tech companies could easily not target kids if they wanted to, but they don't. That may be true, but I don't see why violating everyone's privacy is the only way to prove it.
As Stated Elsewhere you have to have a thing before it can be violated. Given the comprehensive scope of digital surveillance performed by tech companies, you can't claim to have privacy online. And before you "but but the government" they can already subpoena your entire digital existence at will, assuming Palantir or some data broker hasn't already sold it to them. So yeah, may as well make life more difficult for the companies that make all of this possible, that would at least present a modest improvement on the status quo.
