If you're major concern is copilot : Microsoft sucking up your codebase, you better not be producing open source applications anywhere.

Not a single open source license will protect you. (And it won't help even if they add an exclusion clause for AI).

Hostile forges will help though, unless the forge gets big enough.

Scrapers (SEO bots included) tend to only have a handful of "corner cases" built for navigating sites - if your code forge is actively trying to prevent scraping it could help prevent quite a lot.

Your choices remain important, even if it's not foolproof.
