Not wooly at all. The "abuse" of a "dominant market position" is illegal. Vendor lock in to raise prices above the competitive level or to extend market share is the abuse, and "dominant market position" is well defined through law and thousands of precedent cases in antitrust. (In Europe Hoffman-La Roche vs. Commission is one of the cases defining it.)
