On TV and Radio (ie Broadcast Media) in most countries in the world, there are rules on how many ads (or limit on total duration) broadcasters can show per period of time.

Big tech bypassed those rules claiming the internet has so much choice unlike in the past were Broadcasters were few. But it never mattered that the internet has more choice cause Total Available Attention of the consumer is still the same. And if a significant amount of that Attention bandwidth is dominated by Advertising/Influence Ops its very easy to manipulate people. Not just kids.
