The difference between big-company and FLOSS UX design, including profit-motivated behaviors (a bit indirectly, but it's definitely there), is specifically addressed in the article, so I don't think that's a very fair characterization.

I actually agree about customization, but that's only part of it, and seems to be pretty orthogonal to what the article is talking about. You can only customize to features that are actually implemented by the system, and coming up with those seems like the harder problem.
