All disagreements aside, I'm deeply grateful for the efforts made to maintain and extend tools like sed. I can't help see posts like this and worry about the perpetuation of open source, and wish I had the chops to do more to help. As I write I'm downloading a Raspberry Pi image for my son's hardware. I'm getting him an Arduino, a soldering iron and a book for Christmas. I'm looking forward to learning along with him. I don't claim to understand the particular flows of code or inspiration, but I don't see how those projects happen without open source. I also don't see how the Pi happens without industrial scale chip production. As I understand the matter, the Pi was developed by Broadcom staff on their own or 20% time, and its production occurs on interstitial time on production lines that could never be justified by a $25 SOIC. Pi is basically a cheap add-on to a massive industrial base. Of course one point of vision is describing a realizable potential not apparent to the rest of us. But vision can and does proceed despite deviations from its perfect realization -- and sometimes is corrected by those deviations. I deeply disagree with RMS' politics, I'm deeply grateful for his technical contributions. I hope the community can always find a way forward.
