In most of the world, it is tough to explain free software and open source. It is like that Ursula K. Le Guin quote, about the inescapable power of capitalism, and how difficult to imagine an alternative to this power, in its time as difficult as it was to imagine an escape from the divine right of kings. But in Gaza, before the Al Aqsa Flood, the expression of this power was different. Capitalism was present, but it was not all powerful. It was easy to imagine an alternative, because Gaza, a self-contained enclosure, was forcefully cut off from the market forces of rest of the world. In Gaza, to teach people about free software and open source hardware, was to teach them how to survive. Because by accessing open repositories, even people with no capital could build a tech scene, could develop new technology. This was Mohammed Abu Matar's life work, which he has had to interrupt now as the boundaries restricting the entrance of the outside forces into Gaza have been pierced. I want everyone who has ever contributed to open source hardware and software, to consider reaching out with a donation to Mohammed and to Gaza, to let them know they are not alone: https://www.gofundme.com/f/protect-an-open-source-engineer-and-his-family
