Here is the link to the original post.
The author Keivan Beigi developed AppGet, a software package manager for Windows. Microsoft reached Keivan to know the design detail of AppGet with a seemingly consensus on acqui-hiring. Then, Microsoft copied AppGet with no credit and launched WinGet. Note that the copy is legal because AppGet is open sourced.
This post at that time elevated to the hottest content on Hacker News, one of the top news aggregators for developers.

This story becomes a reminder. When we are going to share our design details with anyone, remember to consider possible consequences.
