I do wonder how frequent it is that an individual developer will raise an important issue and be told by management it's not an issue.
I know of at least one time when that's happened to me. And other times where it's just common knowledge that the central bureaucracy is so viscous that there's no chance of getting such-and-such important thing addressed within the next 15 years is unlikely. And so no one even bothers to raise the issue.
Reminds me of Microsoft's response when one of their employees kept trying to get them to fix the vulnerability that ultimately led to the Solar Winds hack.
