How was Netscape shut out of Windows?
This isn't really controversial, it was one of the major factors of the antitrust case against MS, and MS didn't argue they didn't do it, only that it wasn't illegal afaik.

Really, the situation Google needs to keep pressure on, to prevent a modern equivalent to what happened to Netscape, was almost acted out with Maps on iOS.
As for whether the case had any merit.. ok? What I said doesn't rely on the case having merit. Like I said, MS admitted to doing this.
