Also, what does it mean to 'abuse' a monopoly position. I don't think its practical to argue that Google doesn't have a monopoly on internet search[1]. When your product name becomes a replacement term for what your product does/is, that just shows how widely used your product is (another example: Q-Tips vs cotton swabs). But how do you prove or argue that Google hasn't abused its position?

IANAL, but there is a legally precise meaning. (Of course, lawyers will still argue over whether a particular behavior meets the definition.) But it's basically, you have a monopoly in X, and you try to use that monopoly to gain you market share in Y.
For example, let's say Microsoft has a monopoly in operating systems. That's OK, nothing wrong with it, because Microsoft came by that monopoly more or less honestly. But let's say that Microsoft uses that monopoly to try to give it a leg up in office apps (maybe by its own office app people learning about OS changes well before release of the new OS, but competitors not learning about them in time, so that there's a period of time when Microsoft has the only office apps that work with the new OS). That's not OK.
Or let's say that Google has a monopoly on search. That's OK, so far. But let's say that Google manipulates the search results to promote Android (say, by making Android phones come up at the top of the list whenever someone searches for a phone). That's monopoly abuse.
Now, what I'm hearing people complain about is that Google uses Chrome to maintain its monopoly in search. As I said, IANAL, but I'm not sure that counts. That's taking something Google doesn't have a monopoly on (browsers) and using it to try to maintain Google's monopoly in search. That's not the same as monopoly abuse. (It's still sleazy.)

I think this isn't any different than IE or Edge promoting MSN or Bing. I wouldn't say its sleazy, just that they (Microsoft, Google, whoever) is trying to tie their products together to make an ecosystem. Like how iPhones come shipped with Safari (another Apple product). But then again, IANAL either.
