I assure you that I dont have nothing against Gaza and its inhabitants, what irritates me is that you encourage to help them, yet you use the language so vague that it sounds more like an advertisement of their "future vibrant community" (yea, without actual drinking water and severe overpopulation, but with computers, sure, sounds plausible), without any clearly pronounced areas where they need help, except of money of course.
If you can't offer that support then I suspect that spreading the word about these projects is the next best thing.
Edited to add additional links, tidy up language.
If you are interested to find out more, I would suggest that you reach out to them and ask them. They have a number of initiatives (e.g coding bootcamps) and its best to understand what they have coming up and where your skills could fit in. Money no doubt would help the GSG organisation but honestly, if you can, I would go there and help on the ground. They need technical mentors more than ever.
