I, for one, recently cancelled my long term Dropbox subscription based on only a few similar stunts they’ve pulled.

There’s anecdotal evidence that others have too.

Not the OP, but 'app dialogs' and their utility/uselessness are symptomatic of the underlying philosophy and business culture which made them a 'requirement' - so if the app dialog is undesirable, it carries implications about the internal environment in which it was developed, which may prompt someone to leave.

alternately: this was the person pushing the undesirable things, and other people pushed that person out as 'bad news', or, this person couldn't push more 'bad things' through effectively enough to his own liking and so left.
