Thanks to many unsung heroes who contribute to Linux (and RHEL)

I recently had an unusual task to check types of package licenses on RHEL 8 server.

I found out that, on an average RHEL 8 server, there were 140 types of package licenses.

There are so many contributors to Linux, most of them "unsung heroes", promoting knowledge sharing without significant personal benefits. They all deserve a praise.

For the sake of proper counting, here is what I found out on RHEL 8 server and count of type of licenses:
