Personally, I have never had trouble with open source software in academia. I find QC extremely helpful and smack in the face of all those costly CAQDASs. In short, I love it. However, some scholars in my circle have raised concerns over its safety on two points. One: Is the data safe, given that qualitative researchers often study vulnerable populations? Most scholars obviously anonymise their data, and I am pretty sure that QC can't access that data anyway. Two: If the data and my analysis can disappear when I upgrade the software from one version to the next. There was another sporadic concern over whether the data could be stolen. Though I never had any problem, I still wanted to know others' experiences with QC
