Seriously, there are literally thousands of projects out there utilizing free code out of compliance with their license. Then there other situations as well. The only one that can take action about the violators is the Copyright owner. If that owner for example passes away it is then up to the estate inheritors to police and search for violators in the faint hope they can do something about it if they wish. That is very unlikely.
No announcement yet.
