It was the first time we recogniced these transients as ns-ns mergers, but there is very likely other events hidden in archival data. Simply put, gw170817 looked fairly boring in the waveband that has good skycoverage, so without the ligo trigger most observatories wouldn’t have bothered looking.
The article states that jackson had some objection to the signal processing done for gw170817, but nothing really about what he has to say regarding the transient found in the ligo-virgo error contours.
