Google is illegally monopolizing online advertising tech, judge rules

I'm confused how this is a monopoly, is it just the "if we define a market as Google ads, then Google has a monopoly problem"? Like defining iOS apps as a market (and somehow failed)?

Even if they play games with the auctions to keep the price up, at the end of the day X company is spending $5 per thousand clicks (or whatever) because they think it's worth it. Google can charge whatever they want, they run the platform, and it's not as if anyone is forced to use them.

I just don't see how you could in the same breath (how the government basically has) that the app store isn't a monopoly, but Google ads are. There's other ad companies, there is no other way to get an app on iOS.

Um, no, the market is obviously not defined as “google ads.” You could bother to do one single search (maybe even with google!) before spewing nonsense.

Specifically, part of the case found google liable for “unlawfully [tying] its publisher ad server and ad exchange” in violation of the Sherman antitrust act. Basically, google has locked down both the supply side (sites with space the sell for ads) and demand side (market of advertisers bidding on that space) so it can play both sides - and (crucially!) it has integrated them so as to lock in both advertisers and publishers. That’s how you unfairly build a monopoly.

And funny that you use the App Store as an example. Two years ago google lost an antitrust case brought by epic games about their android store practices: https://en.wikipedia.org/wiki/Epic_Games_v._Google?wprov=sft...
