Should XChat be included in Trisquel?

I just noticed that while XChat is free software for GNU/Linux it is proprietary software for Windows. This means that if an existing Windows user tries out the Trisquel live CD to find free as in freedom software and finds XChat he or she will assume that if there is a version for Windows that it is also free. In this case there are other IRC clients around that perhaps should be preferred to XChat such as Pidgin which also has a Windows version released under a free license. Note that in some cases perhaps there is only one free software that can do the job that is not available for Windows, such as HJSlit support via lxslit while HJSplit only offers a freeware version for Windows. Anyway it would perhaps be best in this case as well not to install the software by default in order to encourage the adoption of formats supported by free software on several operating systems including proprietary ones. Note that most people use non-free operating systems at work or in school but might be allowed to install software on the computers, so we should also encourage the use of free software on non-free operating systems.
