Update is extortion to buy the app AGAIN! – Pixter Scanner OCR Document Review

Edit 2/17/18 I can't carry all my books around due to a disability so I used to use this app to scan portions for class. I paid for this app, however the developers decided they wanted more money and instead of being honest and explaining why, they decided to "update" the app so it removes all functionality without warning and force me to "buy" it AGAIN! This is extremely unethical and dishonest and I'm very disappointed with the developer. It's understandable to re-evaluate a business model in order to generate income and adjust accordingly, but the means of accomplishing that shouldn't be with an underhanded dishonest approach where you essentially perform an act of theft against customers who paid for the app. If you've improved the app and need to charge for the additional functionality, explain that to your current customers and restrict them from the added functionality if they don't upgrade. If you haven't added enough functionality for it to be of additional value reinnovate instead of being lazy, greedy, and dishonest. The sad thing is I would of gladly supported the developer if they were honest with their intentions instead of resorting to extortion.
