I do think there's a larger discussion about trillion dollar companies just forking a project and announcing it as a new feature for their platform without even talking to the original creator.
If there's anything to improve, "reach out first" will be a start.
It's open source. You don't have to reach out. There's nothing legally or morally wrong with what you did. But you can do better. A trillion dollar company can do better to act grateful to be in the position that it's in. To be seen as a leader in a space instead of as a consumer of free work.
