possibly 1 good argument for open source software is that this kind of depedance on 1 other business generally isn't there. most bigger open source projects have people from various companies working on them, so relying on that software is safer cause it doesn't depend on just 1 other company.
having said that, this isn't always the case, but in many situations bigger open source projects that are widey used it is.
