On the other hand, most parents don't let their children drive cars either and yet they let their children access those technologies.
Another way in which that analogy doesn't work is that it's illegal for children to drive cars, but it's not illegal for children to access those technologies.
Furthermore, these technologies are being created and modified in a way that are specifically attractive and addictive for children (as well as adults) and they are constantly being further optimized for that criteria as well, almost every day (in a manner of speaking).
This sounds like one of those made-up tweets that became an article that became an urban legend.
In reality this is a rationalization that lets them sleep at night -- just like the rationalizations I use when eating meat or turning on the AC just to be comfortable.
Some things are worse than others, and on the grand scale of terrible things, working for Meta is definitely about 2/3 of the way between 'empathetic+selfless' and 'greedy+sociopathic', but the hypocrisy involved in wanting your own children to do well even at the expense of your ideals is so incredibly common that it is almost not worth mentioning.
