“Community” is a very flexible word… in commerce it often seems to mean “all the users of this product” with the idea that they will help each other to some extent, and so reduce the support cost or improve the sense of there being value in the product. In marketing it can mean “all the people in this market segment that we’ve identified.”
Personally I prefer to use it when I mean “a group of people who share some circumstance and are by default well-disposed to one another and likely to interact positively.”
In a discourse context I might be more likely to speak of my userbase.
