Why am I seeing this capitalist apologia on a pirating forum?

It makes them 'scammers' because:

• they are calling it a purchase, but its not a purchase. It's a lease.
• the rental price is arbitrary anyway. It costs them the same to stream the media, if it's $25 or $0.25. Hell, it costs them the same if they stream it as a purchase as it does to stream it as a rental.
• you don't have any legal option to control your own digital full res copy of any media that you pay for, but they take your money anyway so you can pretend that you do.

I consider that to be a scam.
