I downloaded it, fired it up locally, was presented with a login screen , closed it, and uninstalled it. Sorry, but I don't log into local software.
I saw that it was AGPL licensed, which was odd to me for something that's supposed to be a client. I don't like the AGPL license because of how overbearing it is, I avoid downloading AGPL'd software, unless its a pure compiled binary. I am probably a little too strict about software licenses, but I rather always have the freedom to keep any forks to myself, don't force me to share code for my one-off project.
You can absolutely not only use agpl software, for free, you can even sell access to it. SO OVERBEARING
If you can't stand the burden of having to share with the next guy that which you yourself were given for free, there is no reason for anyone else to feel the tiniest bit of sympathy.
Feel free to write your own software and set whatever terms you like. Surely the need to write it and develop it to the point of actually being any good is not overbearing at all.
Or feel free to license software from someone selling it. Surely Oracle or IBM terms will not be overbearing at all.
Do people even hear themselves?
