Read the whole comment: i said these are problems every long-running software project suffers from, regardless of being a cathedral or a bazaar.
Do you think turning a cathedral into a bazaar is a minor architectural change?
You'd be surprised at how well a bazaar fits _inside_ a cathedral :)
It's been twelve long years that OpenOffice moved from the cathedral model to the bazaar model. And it still suffers from the same criticisms you level against Office and more.
