demonstrated any actual competency in this domain
It may be that he/they have significant competency in this domain, just not publically or under this name/pseudonym.
I’ve personally made contributions under pseudonyms just to avoid employer paperwork/approvals, for projects that I’d rather not have my real name attached to, and for sharing in potentially hostile communities.
I’ve also developed software internal to companies that has never been released publicly.
In short … he doesn’t need to prove his prior credentials to you, me, or anyone. He may have some, he may not.
We can legitimately critique what he/they have done in this project all we like though.




why get up in the morning, only to have to do it again tomorrow?
why paint a still life, when you can just stare at the real thing for a while?
why not hunt and forage your own food?
why not make your own clothes?
why write boring code, when you can get someone or something else to write it for you?
why contribute features that you think are interesting to a product that you use and enjoy?
why post on social media, rather than doing any of the above?
