The growing image-processor unpleasantness
It seems to me that what the FOSS world needs in order to succeed is an extreme push towards forming a class of programmers specialized in reverse engineering. We already have plenty of capable coders who have written so much useful software, but does is matter if we can't use all the hardware at our disposal? Our devices are filled to the brim with accelerators, sensors and assorted specialized hardware that we could be taking advantage of, but they are all buried behind proprietary drivers or just plain inaccessible firmware.
