The more you talk about this as if nothing was your fault, the more this issue stays live, the more you will see people like the company walking away from you and the worse it gets for your own mission.

If they want to destroy your project, I can tell you: they are winning. You are doing exactly what they want. All they need to do is to keep you poking this issue forever and every single one of your users will slowly give up on you.

Take it from your user. We don't like this. If you are right and they are your enemies: stop enabling your enemies.
