The biggest issue here for me is that you're charging for this app. You're basically asking me to pay you for your hard work of removing ads from someone else's hard work of creating content.
It really would have been an attractive project to play with. But it looks like you just wanted a 'snatch and grab'.
Again, well done: You did the work but I wont be participating.
If the content provider offers it, and I want to give it, cool.
But paying for this, has nothing to do with the provider.. At all actually. All money goes to someone who filtered out Adverts, if you wanna have a better argument you could say : can't anyone do this: And yes, but its the time and effort that goes into it, maybe release it open source and free so others can build a network of methods to remove more ads and even support the content provider without them needing to invest in a 'special ad-free' streaming service.
Nobody is telling you not to use this, just their own reasons for not.
