With competing companies the result of one is often at the expense of the result of the other. There is nothing wrong with that if there is a 'level playing field' and therefore the starting positions of those competitors are equal. Certainly in markets where the number of suppliers is limited, price or market sharing agreements, concentrations of market power and behavior of dominant parties can distort market forces properly.
Therefore regulators that protect the market act and promote the interests of consumers by business inspections and punishing misconduct. The risks companies face are therefore an important factor in strategic decisions but also in daily operational and commercial decisions.
