Anyone else had a discussion post rejected on PH with no clear guideline violation?

I recently submitted a discussion post (topic: security risk of ecosystem lock-in with password managers) and it got rejected. Went back through the community guidelines afterwards and honestly couldn't pin down which one it violated - no product mention, no promotion, no spam, just a genuine question aimed at makers and users.
I am curious how others here dealt with a similar situation:

Did you appeal, and did it actually go anywhere? or Did you just rewrite and resubmit without knowing what was wrong the first time?

I am trying to figure out if this is a broader pattern worth raising with the PH team directly. Thanks for your comments and contributions in advance.
