So wrong and unethical

I cant believe Im being asked to pay a monthly subscription for this app or Ill otherwise have to deal with ads when I ALREADY paid for this app a long time ago in order to get rid of the ads! How can the developers do this in their right minds? Something is very wrong about this and I hope they reverse this bad decision. They are going to lose a lot of their following.
