Since you have forgotten what we are discussing, you made this claim:
> The internet can provide an immense amount of good for society, but if we net it on overall impact, I suspect that the internet has overall had a severely negative impact on society.
I am disputing the claim the net effect of the Internet on society has been severely negative.
> That people don't see anymore ads than they used to,
This seems hard to measure and the results would depend on how you define "seeing more ads". The result is irrelevant to your argument though because the one study you cited looks at ad spend, not "the number of ads people are seeing" so you can't generalize.
You've staked out a very strong claim here but have done a very poor job of backing it up.
