Almost touché. Almost. Except you are forgetting the "do it yourself" part of my sentence.

I am sure you can provide one such example for every ten examples I can give you. And I concede that yes, there are exceptions both ways.

But look at the most common reasons for abandoning projects. Why are commercial product abandoned? There are usually two reasons: a lack of resources and a lack of commercial success. Both are justifiable reasons IMO. Maemo is a typical example of the latter.

Why are Open Source projects abandoned? Again two main reasons: something new and more exciting came along (Unity, Gnome 3, Wayland, QML) and politics including personal disagreements (Open vs Libre Office and now Own Clown). None of which is excusable in the eye of the customer.
