PURCHASED streamed movies from Amazon

H Has anyone else encountered Amazon's latest money making move?

The last time I accessed my PURCHASED streamed movies from Amazon, I encountered commercials!

I would have thought that, seeing as how I PURCHASED these movies I would not have to put up with commercials.

I mean, do I own these movies, (that I paid for), or does Amazon?

And if I own said movies, is there any way to access them without going through Amazon?

I am already paying for Amazon's   PRIME  and now I have to put up with commercials?
