0-5? What are you talking about? He was 0-2, got cut, picked up a win at Titan, came back and has been with the UFC ever since. Since you seemed to have trouble with the Bones analogy: my point was that if popping for something invalidates a fighter's winning streak, then Jon's resume is in trouble considering he has popped multiple times and his entire resume is one long winning streak.
I couldn't care less whether you think what happened with his daughter should have any bearing on if he stays, but it's adorable that you think you have a say in the matter. In the world we live in, Dana White got himself and the company heavily invested with the kidnapping and subsequent murder by donating money and promising to support Walt and his family. It would made national news. In the eyes of the company, it would have been a bad move to immediately cut the dead weight that was Walt Harris soon after he got KO'd three times in the wake of all that -- especially at a time when they need good PR. Letting him fight out his current contract before simply not re-signing him is a much cleaner way of doing things for them. It's not like they're giving him a charity title shot ffs, it's literally them doing something they already do with all the guys they already intend to get rid of already and have done countless times before.
Nobody is saying Walt Harris is a Top 15 fighter lmao. But the sad truth of it is that he still has a better resume than a lot of guys who make the walk for the UFC what seems like every other weekend: Parker Porter, Chase Sherman, Justin Tafa, Josh Parisian, Don'Tale Mayes, Chris Barnett, etc. I would love to see the UFC trim the proverbial fat and get rid of all its middling journeyman and just have nothing but elite killers running around, but that's not a practical expectation of them. Especially at Heavyweight.
