"The most I saw downloaded was their Win32 release with around 160k downloads"

Firebird is very commonly used as an embedded database in an application.

For example we have a free software product VisibleResults (Fundraising application) that has been downloaded several 1,000 times and it uses Firebird.

So there are lots of applications with lots of installations out there using firebird. I have very little idea about the size of lots.

But anyway I don't quite see your point. By most scales Firebird is an active free software application of appreciable size .

At what number of downloads are you saying that names should be respected?
