Someone could patent a technology required for implementing a format,
publish an open-source implementation, and wait for the format to gain
acceptance -- the more widespread the better. Finally, when everyone is
used to the format, they start collecting license fees.

==> A format is not any more or less free because of free

It's not that hypothetical, by the way. Unisys started to ask for money
only after GIF had become really popular. (GIF is an image format that
uses the LZW compression technique, which had been patented by Unisys).
