So the guy gets his self-esteem shoot. In the meantime, if wget had been used, with its GPL license instead of the MIT-like license, those products would have to come not with a notice and his email, but with the sources of the derived work, that would allow customers and users: 1- to check that the software does what it should do (and for example, that it doesn't fudge the pollution benchmarks), 2- to hire programmers to correct bugs or add features to that software running on the devices they OWN, 3- to learn about those systems, and generally allow them or the providers of their choice to perform maintenance, instead of having to use the authorized maintenance and tools if at all possible, amongst other things.

So, good job man on your self-esteem shot, but too bad for the rest of us, customers or programmers, you only helped the shareholders of those companies.
