In 1990 Microsoft hired all of the important talent from Borland who up until that point had been outpacing them in terms of product development.
We got Access, Visual Studio, and .Net / C# as a direct result.
Borland faded into obscurity.
Hard not to feel like there will be a parallel here.

Yep, if you wanted to move to MSFT from LinkedIn or vice versa, you needed to re-interview although finding a job rec and internal hiring manager was easier.
