So you're going to love this.
The CEO of Zoom is a former senior engineer on WebEx, funded by ex-WebEx employees and founders.
Zoom was originally him plus 40 software engineers in China.
If I was Cisco, I'd be wondering how much code was copied into Zoom.
And if I were you, I'd be wondering why people are using an essentially Chinese communications tool.
Zoom is not a normal US company that outsources to China - the entire development team started in China with a San Jose "HQ" (because Cisco is based in San Jose.)
