As with many things - forks being my main example - there are production variations to be taken into account, but with dropper posts, I've talked to a couple of brands who've explained that they intentionally limit the amount of lubrication on the seal head initially because of the optics of a "leaking" post if there's an excess that purges.
There are a number of posts I've seen working in a shop that were much less smooth than _this_ Highline 11 initially that were significantly improved with a bit of Slickoleum under the seal. Certainly, as with other dropper posts, _this_ Highline 11 was also improved by adding a bit more lubricant.
Anyway, I'm waiting to hear back from Crankbrothers with more information about their use of carbon for this application but my own experience does make me raise an eyebrow at the quote you've shared. Not saying they aren't experiencing what they're experiencing, but what steps did they take to say whether the issue is assembly v. the carbon shaft?
