This is literally true and goes beyond security. I hope everyone who complained about Google Reader takes note of this; once you have the freedom to modify and rebuild you are trivially able to continue using your software long after the creators have shut it down.

I'd even go further:

Closed-source operating systems/software solutions are dying a slow (too slow) death.

I don't buy this. Unless by slow you mean "heat death of the universe" slow. This is like the "open always wins" argument - wishful thinking devoid of evidence that caters to "If I want it it shall be".

Apple and Microsoft continues to grow. Samsung too, and they have little to no interest in OSS. Let's also keep in mind that most of the world's core services above the OS (eg Google's mail, docs, search, plus) remain closed source, as is the UI layer for most mobile devices (very, very few use stock android.)

Where OSS is doing very well is in commodity infrastructure - browsers, servers, databases, middleware, etc. It hasn't killed the closed source markets there conpletely, but it has made them work a lot harder.

Lets see who is going to pay those developers when they cannot sell their skills any longer.

Not all type of software is amendable to consulting/trainings as means of getting money out of it.
