That's a definition of the word "fix" with which I am unfamiliar.
He still doesn't have access to his accounts.
If a sympathetic police department had not offered to navigate the (likely complex) process of restoring their copy of his data to him, he would have little hope of recovering the data, either. (My hat's off to whomever made that decision, because my guess is other considerations would almost always prevail.)
If federal investigators had not been quite so favorable in recognizing the nature of the situation, that component alone could have easily ruined him.
I'm also unaware of what his legal and other professional fees have been in all this, but I would imagine Google has done nothing to reimburse him for his expenses, much less compensate him for the time wasted and incredible stress that had to place on him and his family.
Beyond all that, getting SEO bombed as being potentially involved in the production and distribution CSAM is not a positive outcome for anyone who values their privacy or wants to ever have a normal interaction with a new employer or any other entity that may search his name. Beyond that, those who regularly fill out official forms relating to background and behavior will forever have to answer some questions differently and jump through the additional hoops an experience like that would trigger.
His outcome has been one of the least-terrible possibilities, but I hope he sues Google in a very public and embarrassing way, because whatever damages are awarded will be a rounding error to them.
Finally, the process itself is by no indications anything but still completely broken.
Your suggested "fix" is anything but.
