One cannot simply open source without picking a proper license.
I wish there was a good 101 on licensing for developers. There’s a lot of misinformation around GPL being bad. Open sourcing your tiny web dev hobby project as MIT or CC0 may not matter in the grand scheme, but a solid library or novel algorithm, maybe you don’t want a megacorp forking it with no acknowledgment or compensation for your time and effort. Maybe the dev philosophically wants their code to be ‘free’ and pass on that freedom. A lot of content just says to slap on MIT or a BSD Clause without talking about middle grounds developers might be interested in either like LGPL, MPL, or even Apache.

Clever.
