Every library my team has ever included in a project has gone through rounds of evaluation to make sure it is 1. publically trusted, 2. well tested, 3. and still in active development. I have no idea what this has to do with mindlessly copying code.

so you invent your own code/algorithms for every project?

If you’re going to submit an algorithm that isn’t maintained and you don’t know how it works, I’m not merging your pull request.
