The notion of “free” in FOSS – Free and Open Source Software – is commonly explained a “Free as in free speech, not as in free beer”. In practice, open source software is often provided literally for free – as I do with my plugins – and this is often referred to as “It’s free as in ‘free speech’, and as in ‘free beer'”.
Now, I have the impression that when “beer” is free, the waiters’ service is considered free as well.
With software, that service is support.
You are willing to give the waiter a tip, aren’t you? What are you willing to give to the open source software author?
Do you donate to the authors of plugins and themes whose hard work you use? Do you link back to their site? Do you bookmark them in social networks? Do you blog about their work?
I suggest the next time you ask for help about an open source package, try first to answer for yourself what that help would be worth to you. If your answer is “nothing”, ask yourself why you waste your and their time with worthless matters.
Now tell me, what is open source support worth to you?
