imho. (!) FOSS every time ...
even if its far worse than a comparable proprietary solution ... as long as it fits my use-case :))
but don't get me wrong: there are a lot of use-cases out there which are best solved with proprietary products - and that's absolutely ok ;))
and especially as a company i should pay in one form or another for either solution!!
as a private person this is optional for me: but no FOSS-project will reject a donation or an order of some of its merchandise - if available ;)
just my 0.02€
