I agree with your main point, but not the Microsoft example of abuse: they forced everyone using their popular OS to use their web browser

They didn't force anybody. One of the first things I would do with a fresh install of Windows back in latter 90s was open IE to download Netscape. Having IE on there made it enabled me to easily learn about and get different browsers. I don't understand how that is so bad. Where was the antitrust on Winsock? What? Forced to use their TCP/IP stack?! Consumer-based OSes should have certain software by default.

Wasn't this more a bit of prescience on Microsoft's part? I mean, now we have Google developing a "browser" OS. Can't get much more coupled then that. What if that becomes the monopoly OS in 5-10 years?

It's always the details that matter.

Shipping the browser wasn't the problem. The problem was that they stopped system vendors installing Netscape and/or making it the default browser.

Doing that is fine if you are in a competitive market, but if you are a monopoly then it's anti-competitive and abuse of market power.
