Founders don't really have much control over what the tools they create wind up being used for.
Assume that some people will use any tool you encounter for the worst thing it can possibly do.
If the tool has significant potential to do things that bother you, don't use it.
Acts of God are a better model for that than business decisions.
Some users will abuse the snot out of it, and a small start up may not even realize that's happening for months.
The founder may not retain the authority to control decisions about what changes to make to the tools or how to monetize them.
Hackers may break into the servers and use the tool for their own ends.
And, yes, often enough the founder themselves will throw the users under the bus when push comes to shove.
