There are things we don't know: a) the cause of death and b) IF it was suicide, the reasons behind it.
It seems logical to assume that it was suicide associated with the recent news explosion, but that is still only an assumption.
IF it was suicide, then I see parallels to a story playing out in the equestrian world, where a well respected top rider committed suicide while appealing a Safesport conviction.
Obviously there are differences - the nature and severity of the charges are completely different in the two matters, and the details of the Rob Gage Safesport hearing and allegations were kept confidential, while here the investigation played out in the open. But both are similar in that an athlete committed suicide while under tremendous pressure and stress from an examination into allegations of misconduct that was discussed heavily on social media.
In both cases, it's possible to use the suicide as an argument against social media, or even against the fact of the investigations. I think doing so is a mistake. Misconduct needs to be investigated, with penalties invoked where appropriate. Allowing allegations of cheating to go unexamined for fear of how the subject will respond leaves us nowhere as a sport.
As for the social media aspects of this matter, I believe that in cases of alleged course cutting, sites like Marathon Investigations and the Meza thread on Letsrun serve a similar purpose to class action plaintiff's lawyers. There are situations of misconduct where the party with standing to act (the race management in the case of the LA marathon, or an individual in a class action lawsuit) does not have the resources to do so. Marathon Investigations and the Letsrun thread, like a class action lawsuit, fill that gap. I feel that road racing is much better off as a result of the strict scrutiny that suspicious performances have received over the last few years.
