I like the definition of anticompetitive behaviour that revolves around using power in one market to squash competitors in another. Example: back in the 90s when Microsoft found itself at the pointy end of an antitrust effort, they did things like: - Restricting OEMs from installing non-Windows OSs - When they didn't restrict it, they effectively did by having more favourable pricing per license if Windows was the only OS you shipped - They did similar things with Office but it was less egregious - Restrictions on preinstalling Netscape - Restrictions on default browser - Using Windows to hinder competitors by breaking existing applications, giving a head start to MS software or moving core functionality into the OS (as they tried with IE) Here are some theoretical examples of what anticompetitive behaviour might look like: - Making AdWords usage exclusive (ie you couldn't also use Bing's version) - Making Doubleclick exclusive - Making either effectively exclusive by providing preferential pricing for exclusive use - Making use of one ad platform require use of another Antitrust doesn't exist to protect competitors from competition. People forget that. There are (many) competing display ad platforms. There's less competition in search (and thus search ads). But you can create your own search engine as Bing and DDG are witness to (plus all the dead ones). It's just that all the other search engines suck. Or, perhaps more accurately, Google is seriously good at search in a way that's hard to replicate. I personally don't think we should go down this road of dismantling companies just because their competitors suck. That's the Yelp business model. Yelp hasn't changed in 10 years. They have so many missed opportunities. But no, "Google is stealing our content". Microsoft has the financial muscle to fund a search engine. They do of course. But Google is much better. Just because Microsoft sucks it doesn't (necessarily) mean that Google is a problem.
