content: I am somewhat familiar with JAWS and NVDA.  It's a situation where it's somewhat like Microsoft Office vs LibreOffice.  JAWS has bells and whistles that NVDA doesn't, and JAWS is the de-facto standard, so if you're seeking employment and you know JAWS you'll fit right in, but NVDA (in the USA) is rarely seen. The whole disability industry is very expensive, and it may seem like a rip-off but I don't think these companies are making obscene profits due to the generally low volume of sales.  I'm all for free and open source software, and people do have a choice.  The blind community is increasingly on social media etc so it's not as if they're being held hostage by the vocational rehabilitation system or whatever. It's shocking how expensive things like braille displays are, but China, Korea, etc. bringing products in have shaken things up a bit.
