I get the point of the article, but I think the author is misleading, biased and in some cases nearly flat-out wrong.
For the sake of brevity, I'm going to just cover some points of contention:
TrueCrypt was NOT closed down due to its software being insecure. They closed down due to unknown reasons, possibly due to US governmental security agency interference. VeraCrypt uses nearly the exact same code as TrueCrypt, and its core encryption was not compromised nor is it insecure: http://arstechnica.com/security/2015/04/truecrypt-security-audit-is-good-news-so-why-all-the-glum-faces/
"I really want to see open source succeed on a much grander scale than it ever has. But much of what open source represents is a mere collection of little ships, sailing endlessly, without an end in sight or a destination to reach.
If you don't know where you're heading, how do you know you've gotten anywhere?
That's a good question -- and one that the open source community just doesn't know how to answer succinctly, yet."
His perception is the problem; FOSS isn't on a singular destination path - that's part of the main point. There's not one or two main distributions of a singular operating system, a singular office suite, a singular text editor or audio application. There's a whole host of varying programs, applications, distros, etc. that range in focus on one or two tasks to being your main desktop to being a stable and reliable server OS.
We're not a fleet of ships; we're a collection of diverse persons, technologies, etc. that share a similar philosophy of open-source. We're not going
anywhere; we're a community - and like any community, there are problems and successes, varying personalities, and fluctuating loyalties.
It's really easy to disparage this as somehow broken when you compare it to MS and Apple ecosystems; but those don't follow the same philosophy. MS and Apple are selling a product and are trying to make a profit; Apple only focuses on specific proprietary hardware for its OS, and MS utilizes its own proprietary document formats. Conforming to your own creation for profit is a LOT easier than creating a product that conforms to other, consistently changing (and not open) standards.
I admit that FOSS has a lot of issues and difficulties - but we should address them accurately, correctly and without distortion.
