I tend to agree, to a point. Fans are ultimately powerless to prevent owners doing what they want, but that doesn't mean they have to sit there mute and simply accept what's happening. The problem I have is that in too many cases, fans only wake up to disaster once the damage has been done. If they think their club is being run into the ground then the time to invite scrutiny on the owners is before it's too late. Unfortunately, this tends to coincide exactly with the period in which a club is enjoying its boom, which means anyone - be that fans or local journos - pointing out that the success is based upon unsustainable spending and a bust is about to follow is invariably called out as a 'shit-stirrer' by everyone else (normally the people who started showing up when the club started winning). By the time the wheels fall off, it's too late to do anything useful.
I'd hope that going forward, post-Chestnuts, we can protect ourselves from such problems by adopting a model that guarantees the presence of at least one responsible supporter director sitting on the board. And by 'responsible', I don't mean some glory-hunter who wants a blazer, but someone willing to veto any irresponsible spending suggestions - even if that seems to the detriment of our chances on the pitch.
