maybe is better if they will apply different prices based on the country where they operate, based on fact that even 1$ can be a lot in certain countries
This is certain. For different countries there should be different prices. Since a person will prefer a pirated film than pay a large price for it.
I think the intention was also to focus on low income countries first. And i believe this is smart, that is a market that can probably use a streaming/Netflix type service, but can't really afford Netflix.
Today it is not easy to use different prices because it is hard to identify where the user comes from. It is easy to fake the country where you access the internet.
Maybe the language could be a chance to use different prices.
To use a ID to set the country would have a good result but needs lots of effort before watching a movie.
If they are offering different prices for different countries what would someone stop from using a VPN to get the cheaper price?
