I definitely don't. I definitely applaud efforts to improve things (relationships, companies, ...).
But going public ("airing your dirty laundry") is a kind of an ultimatum - "I have no other option to enforce what I want than to public shame" - and, while potentially effective, it's also damaging for the other party (and, ultimately, the "whistle-blower").
And at that point, it seems that the values are already so misaligned (whether the employee, or the company, changed is ultimately not relevant) that "divorce" seems like the only option. I definitely wouldn't want to stay in a relationship with someone if they intentionally hurt me (regardless if it was "my fault" or not).
