Got any examples?
I tried running my own "stack" for a project I wanted alerting on. I landed on Jaeger all-in-one (wasted time on Zipkin, the UI just was nowhere near as good as it ought to be) Docker container in docker-compose with COLLECTOR_OTLP_ENABLED.
We offer a free trial and don't charge per a seat.
This business model is only bad for a company if they're not confident that the value they bring isn't enough OR if there is a plan to ratchet up prices, once customers are locked in. If the agreement is transparent, then there's no need for this kind behaviour. That's why at Coralogix, we openly encourage our customers to use an open source integration, and we keep them around with 30 second ticket response times and 40-70% cost savings, without any performance or feature sacrifice :) https://coralogix.com/docs/opentelemetry-using-kubernetes/
