>> The problem were with incentives to have it as the only browser on preinstalled system.
Notice that Netscape was NOT preinstalled with earlier Microsoft OSes either. Customers had to go and explicitly get it from Netscape (download, or snail mail)
The fact that with Netscape 4 and Internet Explorer 4 they did not bother tells much more about Netscape 4 then it tells about evil Microsoft's plan.
>> You are basically saying that it's Ok to jab someone couple of times with knife in the back if said someone is on a bridge with a stone tied to the neck. No, it's not Ok to do that even in this case.
I am not saying any of that at all. I just do not thing that what Microsoft did was somehow jabbing a knife into Netscape's back. Yes, they wanted to control what their OEMs put on pre-installed systems. In fact, Apple wanted to do it so hard that they eliminated the OEMs altogether. Nobody is crying anti-competitive behavior on them over the fact (or did I miss it?)
