To be fair, Elonco does not have service/product now over the poles, it is sometime in the future. I don't know that we know when "the future" is for production level Starlink coverage over the poles; best guess is it will likely require 6-8 dedicated launches which will surely be de-prioritized relative to filling out the primary constellation for something like ~>20° or >25° production service. The 10 polar Starlinks are really just on a pathfinder mission. They're all in close formation in the same orbital plane, which is all but worthless for users (they're currently over Africa right now)
OneWeb currently has ~146 production sats in polar orbit, all which concentrate service at high latitudes (hence the >50°). 3 more launches gets them production level coverage.
