Preserve copyright notices and licence files

[zefir-git]

Comments containing copyright notices are currently being stripped from code. It would be preferable if comments that include the word ‘copyright’ were preserved.

Many licences, such as the GPL family of licences, explicitly require that the licence text be included when redistributing code. Given that npm packages always contain these licence files, it appears that esm.sh may be either removing them or failing to make them available.

As this service is not opt-in, and package authors do not grant a special licence to esm.sh, this practice may constitute a violation of copyright law.

I am not a lawyer, and this is not legal advice. I am raising these concerns based on my understanding of licence requirements.

at least we don't strip license comments in code:
