I have been having the same experience. If you starred a GitHub repo, and they think that their product is similar, they will send you their spam. I condemn this! They should be ashamed!
After 25 years on the internet dealing with spam, it would never even occur to me to invest the energy to write a letter to the offending companies investor. But more power to them I'd say!
