A different quote from Linustechtips.com
The CoC adopted by the Linux Kernel team is called the “Contributor Covenant”.
The problem with this is that the author of this CoC of it has spent a considerate amount of time tracking down developers, looking through their history and then if she does not like them (for example if they have differing political views than her) she has gotten them banned from projects.
Basically, if you for example mentioned on Twitter that you voted for Trump, she might track that down and get you banned from working on certain open source projects. Here are some examples of similar things happening (people getting banned from projects because of things they did on their private accounts.
Would you want a group you tied your professional reputation to being able to ruin your resume, your career and your life for private opinions or one’s political views?
All while the vague code of conduct leaves plenty of room for “you’re a meanie, you’re an evil bigot, let’s ruin your life but keep your work” ...
Hence the threat to pull one’s code.
Thank you for the comments.
