@silverpill as a EU taxpayer let me tell you that I would rather my money go to Matrix than what's being paid to Microsoft.
I thoroughlyagree with TFA that "all open source software" used/planned to be used in the EU or individual national organisations needs to receive funding to the same extent as the for pay equivalents.
And finally, as an open source developer myself, I find it in poor taste to bad mouth others that do the same no matter the quality of their work.
