If you contribute to any open contribution project by Apple, Google, Microsoft, Facebook, etc. you’ll have to sign a CLA first, however minor the PR is. Same goes for some non-corporate projects, e.g. CPython. There are readily made forms and enforcement bots for CLAs at least within the GitHub ecosystem, so you can even deploy them to your one man project within an hour; it’s also not hard to write the tools from scratch, especially considering that drh wrote his own SCM. Therefore, keeping track of CLAs is pretty far down the list of reasons not being open contribution, if it is on the list at all.
