You're mostly correct that the older tech is the bulk of what's been sent, but there have been lots of batches of newer tech that the US has delivered. [0]
These newer companies (Anduril, Skydio, etc.) do it for a few reasons. Some are obvious: they get paid and their systems have a chance at influencing real-world events that the leadership & rank-and-file employees might care about personally.
