Moreover, quote from his article:
> I worked for Replit in Summer 2019, where I was asked to rebuild Replit’s package management stack
What does a package management stack have to do with an open source IDE?
If someone interned as a doctor's assistant at a medical center and then later started their own medical center. Can their previous employer sue them for that? It's nonsense. There is nothing innovative or exclusive about launching a medical center. Just like there is nothing innovative or exclusive about launching an IDE. It's old tech that has been implemented 1000 times. The author is the only one who innovated on the concept by making it open source.
If Replit can sue this guy, then Cloud9 can sue Replit, WebStorm can sue Cloud9, Microsoft can sue WebStorm, etc, etc... Who even invented the first IDE?
Replit was deceptive. They know they are in the wrong and used malicious, unfounded legal threats to scare him into doing what they wanted.
