Does this mean that the "Report on install" feature is already in the old release? It's a reasonable feature to already have, I assume Unity gives you a handful of statistics "for free" as part of using the engine.

However there is a difference between "installs" the number and "installs" the billing number. A website might have 1,000 page views. So 1,000 users? Well we need unique page views. What makes a page view unique? What if someone visits your website but leaves after 2 seconds, do we count those?

In addition to being a terrible decision I don't think the company is prepared at all for this decision.
