I guess bought is subjective here, but ownership is not. And you can still own something if you got it as a gift or through other means. If no one can take it from you (or you need to return it) without your consent then you probably own it. It might be a little vague legally, but we aren't talking about legal issues here (since it's perfectly legal to not have access to the sourcecode of something you own), but rather a perception issue.
