If the linked post is truthful, the issue here is the absolute opacity of the process and the fact that this "assessment" by the credit card network (I notice you used the passive voice "been assessed" - why?) seems very questionable.

I would certainly not trust stripe to effectively "dispute the issue on behalf of their client", based on experiences some of my friends have had with stripe. More likely, stripe just folded instantly upon receiving some automated nastygram from the CC issuer.
