Cons
Con Unsigned and not commonly downloaded
The application is unsigned as it says UAC (user account control) and when downloading in Edge, smartscreen says that is not commonly downloaded and can have malware.
Con Comprehensive
Because of all the advanced functionality this is not the easiest icon editor, so beginners might prefer a more limited simple icon editor.
Con Dependency upon Python2
It is not a 100% deal breaker but Python2 has been left behind without compunction. The average person downloading this will not have Python2. So it will not install nor run. If it could be statically linked or migrated, then maybe.
Con Limited free version
The free icon sets on offer are very limited at the moment.
