Na prvn\u00ed pohled to vypad\u00e1 jako p\u0159\u00edb\u011bh s dobr\u00fdm koncem: n\u00e1lezy jsou venku, provozovatel chybu uznal, nasadil opravy a pokra\u010duje se d\u00e1l.

Vid\u00ed pouze tvrzen\u00ed motivovan\u00e9ho autora a odpov\u011b\u010f provozovatele, kter\u00e1 je sice nezvykle p\u0159\u00edm\u00e1, ale st\u00e1le jde o ve\u0159ejnou krizovou komunikaci.
