In a sense, OTel is a big threat to Datadog, so I can imagine slow-rolling support is one way to manage that without looking actively hostile to it, similarly to how Datadog has other OTel "support" that doesn't play nicely with a lot of their more valuable tools/features.
Datadog has had a number of "come to jesus" moments in the past couple years where they've had to embrace OTel, but yeah, I indeed confess to a inner fear telling me that the Vector acquisition is to prevent tech as much as it is to develop it.
