The one we're in where "software" doesn't just mean an app that someone downloads from a website or an app store. Software includes lots of server side components, etc, etc.
I once noticed my name in the Chromium OS credits due to a patch I had submitted to a library that's on every Chromebook. 1 million would be a small number for Chromebooks alone.
I'm not talking about the median piece of software with 2 users and 0.1 developers (I made that up).
The ones that stick out are actively maintained, widely used, and well funded. It doesn't have to be a million active users, but they should be the first to get their act together.
Unfortunately the number of users and the collective value of their wasted time doesn’t make arguing for efficiency and performance any easier.
