I'm sorry you feel that way. I think it's likely because we've not done a good job in communicating progress rather than what you seem to be suggesting - that Xibo is no longer Open Source.
The project has never closed a single line of source code. It has consistently offered the CMS and Windows Players under AGPLv3 and will continue to do so.
We did have an alpha-quality player for Linux which we could no longer maintain because of the huge stack of dependencies and convoluted build process on which is was built meant that without a team of people to keep pace with the Chromium project, we were never going to be able to deliver something stable. As a result, we took a difficult decision to stop development on that since we knew we couldn't support it going forward.
The commercial backer for the project, Spring Signage, has just put significant investment in to having the libavg integration with Chromium rebuilt around CEF so that we can offer a desktop Linux player again in a manageable format going forward, and that will be, as ever, under AGPLv3. I appreciate we've been saying we will offer a Linux Player for some time, so this hasn't been publicly announced yet since we don't have firm dates at which this will be available.
There has never been an Open Source Player for Android. XfA has always been closed source, and we have never said anything to the contrary. Kind though your donation was, unfortunately the fifty or so dollars the project gets in an average year does not fund the kind of development that Xibo needs to keep pace, and deliver something worth using. Personally I view XfA being closed source and paid for to be a reasonable compromise.
I'd like to think that people would feel assured that we've stated our commitment to Open Source publicly enough times, and haven't given anyone any reason to suggest that we've acted in any way that is incompatible with that.
However, as you say, it's your opinion and you are very much entitled to it.
