how did they acquire this market share? how they acquire it is very important, if they bought all their competitors and dissolved them then yes they're a monopoly, but if they have the market share because they're good and people choose them, then that's not a monopoly.

for example steam currently has 75% of their market, but they haven't bought out their competitors, they are that high for being the best service, and they shouldn't be broken up.

A monopoly is a monopoly, regardless of how it was obtained.
