The biggest competitors in a case like this you can't see, because they don't exist. It's all the competing products that were never created because the barriers to entry were too high.

Are you claiming that they weren't created because of Wikipedia? If you do have evidence of that, then indeed Wikipedia was being anti-competitive. Otherwise, simply because no competition ever popped up, doesn't mean that it's Wikipedia's fault.
