Has negative connotations

Kind of like the name "Slack", which also keeps its product from being uses in enterprise settings? /s

or "Git", which is a straight insult.

Yes, when you have the notoriety, distribution, and reputation-for-insults that Linus does, you can get away with things like that, because you're selling into a culture that already understands the "joke".

My company had what was at the time one of the largest Slack enterprise contracts. You have no idea what internal corporate battles we had to face to get our higher-ups to take us seriously at every stage of adoption, and ultimately roll it out en masse. Slack succeeded in enterprise in spite of its name, not because of it. The actual product was phenomenal, relative to alternatives.

Janky - slang for something shit, crsp, cobbled together haphazardly...?
