Realistically they need to focus that energy on more important things like maintenance and quality rather than shovelling more crap into the inferno that has to be maintained.
The annoying thing about OpenTelemetry is just how underbaked/rudimentary it is, and how opinionated the implementations are.
For C#, I consider Microsoft's Application Insights to be the gold standard. You get per request tracing, stack traces, hot paths, dependency operations etc. with absolutely no setup on your part.
I was looking for an alternative since my current place is on AWS and OpenTelemetry seemed like a flexible, Terraform-like alternative to the platform specific SDKs.
It's not that simple though... AWS doesn't provide any direct sinks to their services, instead you must send it to a collector running in a sidecar container, or if it's a lambda: create a custom layer.
X-Ray's surfacing of the traces sucks as well. It'll only show traces in 6 hour ranges. Hopping between 5 different products trying to find the right metric is not an enjoyable experience.
