It's not completely stupid though. Pondering whether the GPL is essentially communist is an interesting question. Obviously reducing the debate to a beard similarity is funnily inept. 
I suspect that was written tongue in cheek, (or is that Poe?).
To their credit, they correctly caught the copyright pedestal on which the GPL and other copyleft licenses are based.
You would not imagine how many (even very smart) people have a complete soup in their head about the concept.

The GPL can be dangerous in a corporate environment, but many large corporation have processes in place to correctly handle it.
I have been the "Product Owner" for a large and complex piece of SW licensed with LGPL, and yes, core IP had to be treated with care and kept at a safe distance, but we did make very large contributions (and the other contributors are no small fish either!).
As for Legacy's choice (nice band name

), it boils down very much on what he values and how much, here below a summary of options (short and with holes you could drive a cruise ship sideways through).
If he cannot care less, the
WTFPL or marking the code as Public Domain are good choices.
If he cares somewhat, a step up are MIT and BSD: more or less same level of freedom, but a copyright notice must be included.
Apache is still very free (and the one FSF recommends as non-copyleft license), but with more elaborate clauses.
Then we go into the copyleft licenses.
LGPL is good if he wants the code to stay free, but still allow proprietary code to be linked.
AGPL (for server side SW) and GPL: the definitive choice for SW that shall not be exploited without giving back to the community.
Lastly, there's the worse choice possible: no explicit license.
If no license is provided, copyright laws (practically all over the world) imply that the code can be looked at...just barely.
