i respect your point of view but i don't see enough arguments in favor of your opinion. Just pointing out that there is a higher failure rate in open source projects compared to commercial ones isn't enough, especially if you considere that every developer with an idea can start an open source project, which is not the case for commercial's ones. Commercial's projects have teams paid to make the project work, which is not the case for open source projects. And open source projects fail sometimes because there is another ones more interesting and doing a similar thing the previous one was doing. Moreover, with today fast moving technology, companies relying on closed project to keep them up to date are maybe shooting themselves in the foot
