Yes, but is relevant if they are not judged to have a anti-compoetitive effect on the market as a whole. Clearly a company does not have to be a 100% monopoly in the literal sense to run afoul of anti-monopoly laws, but these sanctions are not applied to EVERY company. In Europe, it is not even a matter of behavior illegal for 'monopolies' to engage in, if they are a 'monopoly' there can be sanctions.
