In my opinion, the way PSA has continued to handled this debacle has significantly hurt their credibility as a company who provides a quality service.
Also consider this. In my opinion the '73 Shell looks like an 8, so the latest buyer overpaid by about $3100. But there's also another victim. The 1973 Topps Art Shell PSA 10 is now a pop 2. The other PSA 10 card has, at least theoretically, now been significantly devalued since the supply has now artificially doubled.
