1. In some cases the technology choices aren't mutually exclusive, as you point out. A better representation would be a bar chart that tops out at 100%
2. Not all technologies are equally detectable. The ones that are harder get penalized, and those that or impossible to detect are penalized 100%. In categories where this is endemic, the ones that are detectable appear to be dominant when that is hardly certain. Frameworks is probably one of the most egregiously misleading of the bunch.
