well going off of what edward has touched on...
even if an outside independent training facility could do 'free' what is it they are giving for free that would benefit?
there are certain aspects of the training on brand's that only the factory can give that they simply will not share with the independent training companies. Or if they do allow it that would cost them to even be able to provide it, ie: paying the fees to the mfg to even be able to get their hands on the 'specific' information related to their machines. The only part of training i can think of they can provide for 'free' would be general maintenance which could be performed on any machine.
Any brand specific programs, software, cables, manuals would not be free imo if they even provided that.

I'm not intentionally trying to be a naysayer here but when someone mentions 'free' to me it raises an eyebrow and i take a long hard look at it because in todays world you just don't see companies giving away anything of any 'real value' for free anymore. There is always an angle they are taking to make money and it doesn't take a genius to figure out who pays for it.
