For one, you can just type something in, and get the movie you want. You don't have to navigate between 15 different services, and then find out the film is only available on mail-order DVD, or in other countries.
For television, the networks are HORRIBLE about providing their content to cord-cutters. Want to watch the latest episode of Mr. Robot, which airs on Wednesday at 10pm? You're gonna have to wait AT LEAST until 9am on Thursday morning, WITH YOUR PAID SUBSCRIPTION. Or, you can pirate it for free.
I'm not sure how many times it needs to be said, but Piracy is not a payment issue, it's an access issue.
Also, companies being greedy is a bad look. CBS hiding Star Trek behind their proprietary $10/month service is going to kill Star Trek, because the intended audience sees it as a bullshit cash grab. Put it on Hulu you greedy bastards.
