They have done piss poor of job of explaining the costs vs features. One would think writing a good 5 or 6 solid paragraphs detailing what is going on with it and detailing the costs would be the way to go if rolling out a new program. What they have done is just plain lazy. 

This not even half a-- attempt "how flex works", these three lines,

and a FAQ is all the effort they put into explaining it. There is some video but in many companies there are negative repercussions for watching videos at work.

Perhaps if Autodesk put some effort into fixing the glaring issues with their products like inventor and AutoCAD Mechanical and added the features and controls that their competitors have had for more than a decade they would not need to resort to tricks and schemes. People would prefer using them. For the small guys like the company I work for and the pick up small jobs I am going to start doing the pay as you go and rental is the ONLY thing that makes Inventor or AM attractive. They had better hope SolidWorks never goes to a subscription type model or Solid Edge which does a subscription becomes mainstream.
