Perhaps we're meaning different things by the word 'compete'?
So, yeah in the sense that a five year old Rocky vs Ivan Drago in a boxing match is a competition technically. But no one can honestly say it's really a competition, as in there's any spirit of competition.
U.S. v Microsoft makes it pretty clear. MS'es strategy was break the law and do anything to win. Then it was weather the lawsuit and win or lose, they had years to position IE as the dominant product. So losing hardly mattered they still got what they wanted.
What could Netscape actually do to counter all that? They were practically bystanders in this nearly as much as my grandmother was. Such was MS'es power in the 90's.
"We can't compete, let's make an anti-trust complaint"
"I can't run as fast as Bolt, so I'll shoot him"
No-one will ever know.
