About the linux distros bit, correct me if im wrong: If we add up all personal use cases, we get a number hihger than 100%. Same thing with professional use cases. That means users didnt choose just one option in the survey, but multiple. So adding up all distros will give us an inflated number, where there could easily be duplicates (e.g. someone chose both ubuntu and arch. That should be one vote for linux instead of two).
