I was trying to push a repository on MISP GitHub organisation and got those silly restriction about large files. The repos is actually a feed dataset including the @circl MISP standard feed and its conversion in OASIS STIX format. The goal is to have a diverse dataset for testing import/export and interoperability with an actual real dataset.
Then I remembered that I had a @Codeberg So it seems they don't have such restrictions and rules for large files. It worked well and Codeberg seems to be a nice project.
