Yeah. “Rent-seeking” is just a fancy rhetorical term for “people doing things I don’t like with money”.
Subscriptions are rent-seeking. Loans are rent-seeking. Spending millions in capital to buy a building and renting apartments for thousands? Rent-seeking. Copyright and patents, for sure, unless an AI company is involved in which case copyright is noble and must last a thousand years, because AI companies are rent-seeking.
