That's the ironic part. open source software is supposed to be cheaper than other software, but the NITs are not cheaper. While Maemo is based on open source, and is relatively open, its advantage to the user is not price. The advantage to the user is that it's a better OS for handheld touchscreen devices. Most of the advantages are on the SW developer side. So far, Nokia hasn't sought to license Maemo.
If it had been two words, you could have accused them of jumping to conclusions. For I had always thought it was short for "avoid flamings, not constructive feedback."
