I wasn't expecting them to do something bad for themselves, merely to simply do what I was explicitly asking and paying them for (and we paid above-market salaries). Too often communication was conveniently misinterpreted in obvious bad faith to justify them using some expensive AWS feature, or simply ignore the core message in the request. This was hidden for a lot longer than it should have been since Covid forced us to go remote all of a sudden and people would vouch for one another.
Honestly, I think now that there simply isn't a way to align most employees with you, and that the secret to successful start-ups is only going for the easy to execute things, that don't rely on the qualities of your employees (or you have 100mil raised and your problem is naturally a good challenge for them).
