If he actually did charge money someone else would've written an implementation of sudo to solve their own needs and avoid the overhead of transacting with a random developer.

And then "If he wanted money, he should have charged for his software" would apply to that someone.

And in such a system, before long, we have an ecosystem that resembles the venereal disease masequaraing as an addon store we see in wordpress.

"Your 3 months sudo trial is expiring. Would you like to sign up for sudo-pro (best for hobbiest and small teams), sudo-business (up to 100 users) or sudo-enterprise (reach out for a quote)"

Nightmarish, isn't it?

But that's how the higher-ups at places like IBM and Oracle see the world.

And these people are free to roam the streets unfettered. Hardly seems right.
