"In use since" implies a continuous state of being used from a specific time, whereas "used since" suggests that something was used at some point after a specific time, but doesn't necessarily imply continuous use. For example, “This method has been in use since 2000” versus “This method was used since 2000”. The first implies the method is still being used.
