Full of ‘excuses’, don’t want to repeat, you can google many articles about gpl violation (or not). My opinion is this is bad. Your based on thousand other people’s free/open source work, and added your work, if you want to limit/restrict public access, then don’t use gpl based linux, go back to your AIX. ( This restriction is violation GPL, I know lawyer with huge money can argue anything, so again imo)
