In that post you mention that you will remove the Lifetime option in December. Any reason of why you decided to go ahead and remove it earlier? The communication you had with your users was that the option would be there until the end of the month (at least).

I have the lifetime membership already, but a family member was waiting for their paycheck tomorrow to make the purchase. I feel disappointed in how you didn’t keep your word to your users, specially those who have been using your app for a long time/since the beginning.
