Will they need to rewrite their products to use Google stack?
Not necessary. Case by case basis. Google has EngProd teams for this.
What does EngProd do?
They continue to function with their own stack and slowly transition to internal frameworks. E.g. I know Looker still uses React, while none of (well, from what I know) Google products use React.
Don’t worry. Google isn’t thinking about buying fb.
Maybe they will release another google plus. 😂
