100% this! One of the worst projects to reason about I have ever worked on (and I have worked on a lot of trash) was when a colleague insisted on implementing a state machine in a system that tracked voucher (offer) redemptions. State machines do have their place but coordinating business logic with one is a bad idea IMHO

This same colleague had implemented a similar FSM (flying spaghetti monster as known by the team) in an FX (foreign exchange) platform at a previous company. Which after a job change I got the pleasure of experiencing, nobody in the team knew how it worked and everyone was petrified of making changes
