3 unoriginal thoughts.
1. This is bizarre behavior, especially from the ultra community. I don't know the top-level pros personally, but most seem to come across as near-perfect examples of sportsmanship. They want to win the right way, they respect their competitors, take bad days in stride, and cheer on others' successes. I can't imagine anyone else doing something like this.
2. Editing yours and competitors' wikipedia pages and lying about it is bad, but not the worst thing in the world. It's an embarrassment for the sport, and should be for Conor and Camille, but I don't think it's the same magnitude as, say, doping or course cutting. I'd be surprised if Kilian's been losing sleep over edits to his wikipedia page.
3. I think a genuine apology at the outset might have resolved this for most people who care. Conor's e-mail and Camille's post, to me, made this worse. Lots of excuses, probably not telling the full truth, zero acknowledgment or explanation, "we're the real victims here" tone... There are plenty of internet sites that explain how to apologize. (I don't know enough about Camille's apparent history of going after people who challenge her records. To me, that's a separate issue. I don't begrudge those folks their schadenfreude today).
