@dalem many years ago, i had a conversation with my friend dog star about licensing. i don't remember what my angle was (it has certainly changed with time), but something or other about copyleft vs permissive licenses.
anyways, at that time she didn't bother licensing anything she wrote. she doesn't license anything now either. granted, she's more or less out of the computer thing these days, and more into illegally (based) typesetting and publishing rare unobtainum literature scrounged from god knows where and making ghislaine maxwell very upset. i digress.
i don't really remember well enough what she said during this conversation to paraphrase her anymore. but all my thoughts on the matter are strongly influenced by her. i will not stuff words in her mouth and share my own thoughts then:
ignore other peoples licenses. this is based illegalist praxis. publish your software without licenses. people who you don't want using your code will use your code anyways. the people who you do want using your software are the same people who engage in based illegalist praxis. the people who are worried about you coming after them should get a grip and realize you have no institutional power.
licenses are annoying and in my youth i preferred permissive licenses for this reason, simply because they are slightly less annoying. but ever since this discussion i have simply stopped licensing anything i write. and i also steal code and don't attribute it. stop doing licenses
