@Daniel -Ted’s reply is typical whining from people who gladly take free software, complain when it’s not perfect, and expect not to have to contribute.
Free Open Source Software is not the wilted lettuce and day-old bread that they sit out on the loading dock in the alley, for the unfortunate to pick through.

There is still a lively debate, whether closed commercial paradigms are inherently handicapped, in comparison to open & free ... but GNU/GPL projects have stayed right at the front of the pack for long enough now that nobody mistakes it for second-rate.

No, the implication that of course one will pare off the moldy spots and pretend to prefer soft, rubbery greens, when he accepts free programs, misses the main facts about FOSS.

Matt Mullenweg gives the product away, not just to crummy people and ingrates, but to everyone. And inspecting it for bugs, rot and suitability to purpose certainly is an important role of those who put it to use.
