I'm wondering how widespread this is through out the so-called 'tech-industry'
Good question. But what is "this": support for the aim/intention/philosophy/etc as you express, or the implementation of it as part of for-profit businesses? I'm not part of this industry, but would be intrigued to know (for either).
We all love free information and freedom of information. (Well, I do. And all == me + anyone thinking sensibly). But there's a long line of folk - from Galileo Galilei to Julian Assange - for whom it's been a costly bargain. I think all partisans of freedom should consider doing their bit, and paying some small part of the cost of defending, promoting, and extending free.
