Quoting Highflyer from the previous page:
The pilot's activities preceeding the flight, as well as the activities of everyone on board, are relevant to the investigators. However, until those activities are shown by fact, not rumor or speculation, to be nefarious, it's not fair for the media to present them as such or for the public to interpret them that way. The pilot may be an innocent victim whose grieving family doesn't deserve to see him villified in the public eye for doing such mundane and ordinary things as cleaning up his hard drive.
You say deleting game files from his computer is an oddity. How do you know that? Has information been released showing that he didn't regularly delete old game files? Has information been released showing that those files contained anything incriminating? I clean old files off my hard drive about once a week.
Is it an oddity that his family went to their 2nd home when they did? How do you know that? Maybe they had a habit of going to the second home on a certain day of the week or when the pilot's schedule called for him to be gone longer than one night. We don't know, so we certainly can't say it's an oddity. Maybe not going would have been the oddity.
IMO, it's not fair to the pilot, who by all accounts was an extremely caring and generous man, to villify him with no evidence of wrong doing. If investigators find something related to the disappearance of the plane on his computer, that's the time to release it. Not before.
