I absolutely agree. That's one reason I encourage any group making a show of support to back it with a press release and a very public announcement. That way this story can be show as part of the broader struggle to preserve the 'right to hack" for all of us.
The downside, of course, is creating the perception that Ahmed is being used as a figurehead, and making him, as somebody else said, a "political football". At 14 I doubt he wants all of that. But his story is part of a larger story, and I think we should all acknowledge that and help make that point to the rest of the world who don't realize it.
Edit:
Also, FWIW, at SplatSpace we spend a lot of our energy on exactly that - encouraging young people. We do a lot of outreach with local public schools and the various local library systems. We have done a lot of things like offering Scratch programming workshops, and electronics demos using 'squishy circuits' and taking 3D printers to "math and science night" at local schools, etc. So yeah, I totally agree with the sentiment that we (in the broadest possible sense) should do all we can to encourage and support young hackers/makers.
