There is a free tier coming, so you even if you stopped paying for "pro" you would be able to access any games you had purchased.

This is the same as Xbox and PSnow, etc. You have to pay for the service via a game pass or pro membership on top of buying the game and possibly the system before you could stream it.

Even in the case of shadow, you'd have to pay for the service to stream games you'd buy and access off your own/their system.
