Uh, you can actually buy south park from any number of providers. Amazon and iTunes both list Season 1 for $25. You don't need to only watch things on monthly streaming platforms.
Can you play the media without going through Amazon or Apple to do it? Is the quality guaranteed to be good when I choose to watch it? What kind of ads am I going to get when I click play? Even if there are no ads now, is that guaranteed to be the case forever? Downloadable, ad free, and DRM free. Music has been selling that way for decades. I've spent thousands on that kind of media, I'd have spent 10 times as much…
Most of the time I watch things once, so I rent it if it's not on a platform I subscribe to. Generally then I can watch it on my tv, ps4, phone, computer, whatever.
Consider that money spent on these products are an indication to studios about what people like. Movie studios, production companies, they make stuff they think they can sell for a profit. I suggest that you try renting movies or buying ones you like. If you run into a situation where one of your concerns comes to life, I think it would be very reasonable to pirate something you've made a good faith effort to pay for. This is kind of how I started and now for the most part I rent/buy with some exceptions. Still downloading some trash tv shows.
