Lots in our community want to be able to purchases devices that have all the source code available.
The FSF itself has championed 100% free OS's, and also tried to promote hardware devices that protect users freedom.
If there is binary blobs on a device then whoever controls the blobs has power over "good" developers and their users. The fewer binary blobs the more concentrated that power becomes, and therefore becomes harder to eliminate.
This is becoming more of a problem as software gets distributed in an aggregated form (firmware, images) rather than as individual components.
The GPL says "mere aggregation" of copyleft software with binary blobs is ok, is it still ok ?
Is it time for a new license that articulates the wishes of those who want 100% free software ?
