From your license agreements (this language appears in all 3):
You are NOT allowed to:
Redistribute in any way any of the userTrack files or any parts of the userTrack's source code (with the exception of the public tracker JavaScript files that have to be included on your site).
Install userTrack on someone else's server.
Continue using userTrack or offering userTrack access to others after this license agreement has been voided (either via a refund, license period expiration or legal action).
This is not open source (or even "fair code" as redis etc advocate for). Providing the source but under a license like this is usually referred to as visible source or shared source
You are correct, I did confuse the terms "visible source" with "open source".
The way userTrack is currently distributed is as any other digital product (you pay for it and you are not allowed to sell or redistribute copies of it) with the mention that the server-side code is un-compiled and un-obfuscated so you can transparently see what it does, how it does it and change it if you want.
I am not sure that fully open-sourcing it is the way to go as I've seen so many projects die or disappear because the maintainers didn't have a lot of incentives to keep improving it or simply no longer had time to work on it. I also think that it's fair to pay for something that brings value to you also knowing that by paying for it you support its further development.
