That's not the point. I don't feel like I should have to pay more than what I'm already paying for satellite and internet to watch something from a broadcast (aka "free") network. And if they're going to show the premier on tv, then hide the rest of the episodes in a subscription service, I guess they really don't want me to watch that badly. They're going to lose a lot of viewers who don't give two f***s about anything that's only available through a streaming service. If that's your thing and you're into it, great. They're going to have to make money from SOMEone of this show.
Capitalism my friend. It's annoying to me, but clearly CBS has prioritized growing their streaming service over total viewership. They know star trek is a show that has a built in fan base and some will sign up to watch, like me. So they see it as a way to Kickstart their streaming network.
