Yeah, the answer here is cancel prime and pirate whatever amazon video content you want. if you absolutely have to have prime for some reason, don’t sign in to amazon video on any of your devices and pirate the stuff you want to watch so at least your not contributing to views or their prime video ad revenue.
Edit - I see in another comment you said you unsubscribed, good on you.
That’s been my life for the past 10 years, you won’t regret it at all.
