yes because there's people who can't write but want to pretend that they can, just like the people who don't disclose they're using these tools. If you're the Gwyneth Paltrow of programming you're not making a great case for yourself, and I'd like to know before touching any of the software.

because no person can read every line of code written in software they use, or track every commit made to a project. Integrity and authorship matters. If a person lies or obfuscates the origin of what they produce, an article, software, what have you they're doing it for a reason, otherwise they would be honest. That's not prejudice, that's recognizing deceit. And you don't eat fruit from a rotten tree.
