If this new process of stream conversion requires such "powerful server infrastructure," why is the author willing to provide that at a flat rate? In fact there are applications that perform this function on the user's end at virtually no cost.

The app I use (which I won't name but is easily searched) has this in its free edition, and does the work during the download without ever using more than 5% of available resources. This on an processor manufactured in 2011. A twenty minute 1080p video downloaded and converted in just over 3 minutes. Yet virtually every addon developer claims that the conversion must happen at their end, and they will need to charge the user for this service. Nonsense!

The author has every right to paygate this feature as convenience, but NOT to assert that the feature is necessary to you or costly to him. This is misleading and in my view borders on predatory.
