I think that's a general problem when issues happen.
As long as everything works as planned, they are transparent. But as as soon as anything goes wrong (which is normal for such projects), they stop being transparent or try to hide that something happened.
The Pandora was similar, where the main guy became less and less transparent and told more and more lies to keep everyone calm, which in the end lead to a complete disaster.
That's not always the case. If the problems are solvable within reasonable costs and a timeframe, they'll only cause a delay for the backers and everything will be good in the end.
But somehow, most crowdfunders are afraid telling their backers if something didn't work as good as they planned to. Maybe they're afraid their backers will get angry.
