If I were you, I'd change or delete this comment. You've mentioned specific details which would make it very easy to identify you. And disparaging your company when you are already in a precarious situation is not ideal.
Being fired for complaining about dysfunctional corporate bureaucracy is absolutely ridiculous. I’m not saying someone lying about or slandering their employer should go unpunished, but everyone, everywhere should be entirely free to criticize their employer for valid concerns, in private and in public. Anything less creates a further tilts the power imbalance between employees and their employer in favor of the employer. This is bad for labor markets and can slowly destroy companies from the inside.
I agree, and OP, remember you can use the support email at the bottom of the site for this sort of thing (since you probably can’t edit the comment yourself at this point).
