It's the end of being able purchase any kind of perpetual license to your software. It'll all be on the web and it will be paid per month. When that meets a company with an aggressive sunset policy or if they have an outage it won't be a good time.
One could also see it as an option that makes contributing to open source so much easier for small edits. There are plenty of times when I am working that I would make a small change or refactoring to a project, but the idea of cloning, setting up an environment, figuring out how they run tests, etc. makes for too much of a barrier to entry.
