Re: Seems like a spurious argument
You are missing the point.
With FLOSS software, it is legally permissible to take a copy and maintain it yourself and publish updates to the world. How easy it is for *you* to do that is another matter. The point is it is *allowed*.
With copyrighted software, even if you are technically able to maintain it (lucky you), you cannot publish updates to the world without having permission from the copyright owners. For most people, that is an effective means of preventing progress, so you are forced onto a new copyrighted version, whether you like it or not.
Don't blame FLOSS software for your limitations. FLOSS allows you to do stuff you otherwise legally could not. It might be difficult to take advantage of, but that is a resource issue, not a legal issue.
