"If corporations dominate society and write the laws, then each advance or change in technology is an opening for them to further restrict or mistreat its users."
Also, you definitely can, tongue-in-cheek, call a general statement a "law." It's not meant to be taken in a literal sense; it's meant for humorous or broadly pragmatic effect.
That's not a "maybe" any more by now. Corporation are meant to maximise profits, at the expense of everything else, except braking the law —and even that is debatable. Some jurisdictions even have laws to enforce that mindset.
As soon as profit maximization is at odds with the user's interests (that's pretty much all the time), the corporation will naturally act against the user's interests.
From this, I'm pretty sure "law" is a relatively accurate descriptor.
