(this is gonna be a boring post despite the lede, sorry)
- You work at X company
- X sells Y company cloud services
- Y company is doing something slightly wrong that costs them $xx million / yr more than it should1
is it legal to
- offer consulting to Y to improve cost efficiency of using X's cloud services (after you're no longer working for X)
- everything discussed is public knowledge2, except you only know about Y's infra mistake because you saw their metrics while working at X
-
You've actually informed the account manager at X who manages Y's account about this, but they declined to bother Y with this information
-
all of the services X offers is documented publicly, and this particular kind of mistake is one that people are generally aware you can make, but Y apparently hasn't noticed they're doing it. You're not telling Y to stop using X, just that they can shuffle around how they do things to save money
