Blow your whistle all you want but until something catastrophic happens, the whistleblowers would turn out the way the whistleblowers for the 737ng airframe cracking came out: fired and then ignored.
You can't just start leaking internal documents and making accusations without evidence. ...that will get you fired, and possibly in jail.
You need to talk to a lawyer, follow the legal process, and make allegations that you can PROVE.
So many whistle-blowers come out with wild stories (often true), but since they bring zero evidence to the table they are ignored. ...and if they have evidence, they just blindly leak it to the press without going through the process, which can endanger people/privacy and destroy IP.
Don't get me wrong - whistleblowers are important, but if you really want to make positive change and not just stick it to your employer - do it responsibly.
It feels like the problem is cultural. If the culture doesn't allow enough time for confidence in deliverables, then what proof would you have? Often there are a million items that can go wrong (although all tests pass). So probabilistically something is wrong, but there's no solid item to latch on to.
