I would and always will give precedence for individuals comments over corporate public relations. I read them quite simply as ex-insider frustration, nothing more and nothing less. These people are not burning bridges, they are expressing what would need to change for them to return. Once you have left a company why maintain that companies Public Relations (PR=B$) charade, why not critique it.
You whole point of being subservient and servile to corporations once you have been employed by the them is pathetic. FUCK EM, hate the company you work for, if it rocks your boat, publicly tear em a new one, whether you are currently working for them, you have quit or you are already working somewhere else. Gees, what the fuck, corporations are not gods we must fucking worship.
