We did get absolutely burnt by other manifestations of the DataDog approach: The billing model was (is?) very much not good, transparent or predictable and staying on top of costs was close to a nightmare. The way surprise costs and contract changes (triggered by them) was handled did not feel honest.
The product itself is great but from my perspective it's absolutely not worth having to deal with their business side of things and the risks, costs (money, time, attention) and stress associated.
If I were a Quickwit customer I'd start looking for alternatives.
