That was a lot of text for me still having no idea what the point of the author was (beside what I can infer from the headline that is).
I do however now know that they're a totally cool dude building stuff physically and as software + that other people give them money for it.
Does that have anything to do with the topic suggested by the headline? Not sure.
Everything is an ad these days. The article was not useless, but for the information it provides, it could have been two paragraphs.
FWIW it told me stuff about openfaas. Now I know how to mentally file it and how to mentally file the author. The GitHub profile alone might not have sent the same signal, so this is useful.
Is it bad software? Idk. Probably not.
Should you treat it as a grassroots Foss thing maintained by fellow sane hackers? No sir.
