They'll keep an ad-free option for another $2.99/month per https://www.aboutamazon.com/news/entertainment/prime-video-update-announces-limited-ads

I don’t even pay for prime for streaming. Watched a movie or two on there when it was something I wanted to see and found out it was free on Prime. Otherwise, I use it for the expedited shipping. I did briefly cancel in 2021, but the spouse complained. We split it now anyway, so it’s cheaper. Overall, though the quality of products offered on Amazon has gone way down hill. If the product is something that doesn’t need to be quality, it’s fine, but if you’d have to replace the item if it is not quality, you’re better off skipping Amazon. The value proposition is declining.

Is it possible to have Prime, but without Prime Video? I don’t give one iota of a fuck about their shit ass streaming service.

What does this mean for shows and movies that I purchased? Will they have ads unless I pony up? If I cancel Prime will I lose access to them?

prevent paying more for shipping by not using amazon at all.

I paid for 15 days of Real Debrid and other than running into a lot of non-English streams it's been great. If I can get it convenient to download shows automatically (I've heard of ways to integrate with arr services) I might start cancelling services.
