I'm not sure how your response is actually addressing the suggestion to pop-up a warning. If the company is aware of the issue and there is no technical reason not to implement a warning, even if it would help out only .1% of the users, then why not do it? I would understand if it was some large feature and they didn't want to waste resources, but it's unlikely the case here (undoubtedly they keep track of how many files you have synced and they already have the ability to do desktop notifications).
