The 'anti-trust' and 'monopoly' arguments strike me as hypocritical and self-contradictory in the context of capitalism. We encourage businesses to compete and succeed, yet when they do so disproportionally, everyone suddenly feels entitled to intervene in their structure, policies & processes - and best of all, we have no objective guidelines or criteria for when this should happen.
The question then becomes: who gets to decide when to bring forth these concerns, and what's their agenda? Food for thought.
