I'm not in the US and not on adderall (I'm on ritalin LA), but friends in multiple European countries also have issues with supply of adhd meds. I've been mostly managing okay in France, but for a few months there I was getting Swedish bottles of ritalin, and the pharmacists gave me a little print out of the medication leaflet translated from Swedish into French.
I think that campaigning and investigating the shortages and what is being done is a pretty good cause. Is your issue that by focussing on name brand adderall they're making generics look bad? (I hadn't heard of the reddit community before)
My personal experience is that the quality of generics can be pretty problematic. Lots of the big generic companies are based in India, and are not subject to the same checks and monitoring that the FDA would do for a US based manufacturer. This means that there's the chance that your generic drugs won't actually be as effective, not because the namebrand molocule is somehow better, but just that the quality control is more reliable. On the other hand, I've found Xaggitin (a generic copy of Concerta produced in the UK) to be much more effective for me that namebrand Concerta.
There was a book out recently that was a whistleblower's account of the issue. "Bottle Of Lies: The Inside Story of the Generic Drug Boom" By Katherine Eban, if your interested (you can find some reviews of the book that cover the important parts).
