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.
Datadog is a pain in the ass. I've got two emails and a voicemail from them just this week. We are not an active customer.
Heroku/Salesforce is also a pain in the ass. It causes enough friction with legal that I'll spend whatever effort it takes to replatform our workload just to not have to have those unending inbound calls.
NS1 was easy-peasy, but post-IBM I now receive a PDF invoice for $50 once per month with no credit card-based billing options and have to remind finance to cut a paper check. I'll be rehoming our DNS as soon as we decide on where to move it to.
tl;dr: the business experience is part of the product
