Turns out if you have a VPN and can provide them with just an email address (no credit card required), you can access a fair amount of programming on the service for free. I tested it and it seems to work. I didn't stay tuned long, but I'm assuming the freebie comes with commercials, while if you subscribe, they're removed. There's actually a lot of stuff there in the free mode, but you'll need to have your VPN on and your ad blockers off to see it.
