That was likely the fear at the time, but what we actually saw was Javascript became popular because it was useful and there wasn't really anything else like it. It became popular, so Microsoft threw in with it too. In order for that to have not happened, it would have had to be so unpopular that Microsoft would decide it wasn't worth adopting, but still popular enough to get Microsoft on board with the general idea. I just don't think that is likely; people would have sucked up a scheme-based javascript even if it was a tad unfamiliar; it was that useful. (Not to mention, going with the cynical "three E's" theory of 90s Microsoft, they would have at least first adopted it before perverting it.) I think people overplay the importance of being C-like. AutoLISP hit a bit earlier and found a very strong following in a non-programmer niche. People doing web development were already fucking around in HTML of course, so clearly they could wrap their heads around things over than curly braces.
