Re: "and they're losing faith.'
Ok so I've used the majority of the software you mention (both the commercial and FOSS elements) (minus the CAD/3D stuff - I tried playing with that once and decided I simply didnt have the mind set for it).
Something I find that is often missed in these conversations is skills/training and consistency. FOSS projects are much better than the 1990's and early 2000's but they still generally lag behind, more over because they tend to have smaller user bases the availability of training (as opposed to online learning materials) is much more limited.
A phrase that I heard once is that an amature practices until they get it right, a professional practices until they dont get it wrong (ok big generalisation as I know that pro/amature is about being paid and that there are big skills variances on both sides - but in aggregate people being paid then to be better than people just doing stuff for fun)
Basically what I'm saying is that the FOSS solutions are good, and certainly helpful for home users who want to stay on the right side of licencing. But the dominant commercial products tend to stay that way and to produce more consistent and better quality output for a whole load of reasons which are much more about users than about products.
