Fuck that other site

the GPL’s sweeping liability exclusions might not be enforceable in some EU jurisdictions.1

Interfaces, protocols, and APIs are not always covered by copyright under EU law, depending on their functional nature.

As for MIT licence: its brevity doesn't reduce applicable laws—it merely omits explicit handling of them, which can create legal uncertainty in civil law jurisdictions.

Especially hard is working in a community where everyone accepts a commiter's agreement (contributers license agreement, I guess: CLA), and to handling all author metadata GDPR applies to anyone who handles the source code in a DVCS for non-private purpose. Having a brief licence when the CLA is typically 1 through 3 pages of A4 text is not that much of an upside.

Disclaimer: IANAL.

Footnotes:

The rights holders (authors and/or licensors) shall be liable without limitation in the event of wilful intent, fraud, gross negligence, damage to life, limb or health and if liability cannot be limited or excluded by law. In case of a negligent breach of an obligation that is material for the execution of this osc license agreement (material duty), the rights holders (authors and/or licensors) shall be liable up to the amount of damage that is typically foreseeable at the time this osc license agreement is concluded.

Any further liability is excluded.

Writing this down has nearly no effect, since you implicitly have these responsibilities anyway

I find this Reddit comment useful.
