It's not an overly entitled way of thinking when it comes to a device I own that uses a data package I pay for. I don't actually run an ad blocker in my web browser, but on mobile, where screen size, battery life, and data usage constraints are very real, I can't stand them. If I couldn't remove the ads from an app I would definitely find something else.

As for the downvote, you're right, but it wasn't me. I don't have that ability yet.
