Adtech handles money. It's financial software that also needs to be (soft) real-time. It's harder than the usual money software.

Adtech loses income, not money. There is a vast difference.

Additionally you can have rollbacks - strategy applied by many banks when things break.

Funny enough, safe reverts and rollbacks require specialized up front design, it does not happen on its own. Safe automatic updates with no state loss? Same.

Placing bids is (potentially) spending money. A bug in your adtech platform can absolutely bankrupt you in the very direct way of spending more money than you have.
