Wouldn't be so sure. Observability tools usually have the highest traffic, highest data volume, and highest availability requirements of any system a company runs. The times you need them most tend to be the times all of your other systems are failing, so having a shared blast radius is a really bad thing. In any microservices architecture, they're multi-tenant systems with plenty of noisy neighbors. Those factors make running them well both harder and more expensive than running any ol system.
