100 Billion is a vast overstatement.

In 2018, google sold 118 billion worth of ads. Parent was saying (I think) that all ads present misleading narratives so google would have to ban all ads.

Over a decade, from politics, that amount is high, but not unreasonable.

Phrased in terms of opportunity cost, it's appropriate, again if a bit high.

Media gets YUGE dollars from politics. That flow of money in politics is one of the biggest problems in the US.

Many want to fix it. That risk, in terms of the financial opportunity assessment under discussion right now, would reasonably ratchet that number down further.

Is it though?

> A staggering $24.1 billion of Google's $27.77 billion revenue for Q3 2018 was from advertising – roughly a 22% increase from $19.8 billion in Q3 2017.

Right. All ads are political by definition. So it’s really a ban on opposing ideology, and on overtly ideological ads which are really not so much of a problem. I think it’s a non-change from the current system, mostly a pr move.
