Can we please not call this open source if it's not?

The tool may be great, but the title leaves me skeptical of anything else.

                      A "Tracing and Metrics Service" is a commercial offering
                      that allows third parties (other than your employees and
                      contractors) to access the functionality of the
                      Licensed Work so that such third parties directly benefit
                      from the tracing and metrics of the Licensed Work.

How then we should call it instead, if the source code is openly available?

"Open-source" has a very specific definition which the BSL does not satisfy.
