Well, that actually a very important point. Clearly adoption of free software is much lower than one could expect. What I mean is: you can argue that Gimp is not as good as PhotoShop, LibreOffice not as good as Office, or that Linux is not as good as Windows (which is clearly debatable) but they are good enough and they are all infinitely cheaper (literally) than their paying alternative. So that should be default choice for 99% of people. But it isn't.
So my point is: The same goes for cars vs. bikes. Most people wouldn't mind using a bike to go to work, but it feels weird to pay only a couple of bucks for a bike, when you've learn that the price to go to work is the price for a car.
I was more referring to compatibility, here. LibreOffice is infamous (at least around here) for mangling table formatting used in Word docs. Gimp is hardly feature complete compared to photoshop.
The reasons for this could probably be rightly chalked up to obfuscation and other below-board shenanigans on the part of certain companies, but the end result is still that you don't use the FOSS version if you're serious.
