Both. I’m strongly of the opinion that monopolies should not exist, and if they do it’s the result of illegal and/or unethical activity, and should be fixed immediately. They break the free market and end up hurting everyone in the long run.

In addition to what @Asterisk@lemmy.world said, they also include a forced arbitration clause in their terms of service to prevent class action lawsuits from customers.

Tbh, they’re very low on my personal list of monopolies to hate, so I don’t really have that many arguments ready to go. I’m sure others have made a good case against Steam somewhere on the internet already.
