The vast majority of satellites aren't made for this kind of mapping as far as I know. Of the ones that are most aren't private commercial projects. Wikipedia lists 6 such projects and i doubt their time is cheap enough to make it worthwile for Palestinian resistance. Israel is another matter but they'd probably just knock on the US door for those.

I am a bit surprised however that there would not be more satellites that is commercial operated. I keep hearing about old weather satellites that gone past their period of commercial operation in favor of newer ones, and the old ones still having decent cameras and other sensors to provide maps of buildings and structures. With about 6000 satellites currently operating around the earth there should a pretty steady stream of old ones being replaced, and I would think many of them do get reused for new purposes.

I don't think Israel has to spend much if any. I think the blurring happens based on their request and i'm sure they still have access to unblurred satellite imagery. The only ones that could be hampered by this are the palestinians
