FWIW, LH has a EQM promo right now as well.
And given the decline in business travel, I suspect this is less a case of airlines trying to poach other airline's elites or generate new elites as it is an attempt to maintain the current numbers of elites on their own rosters.
While there will be a few people who will use the EQM promos to gain new status, most will end up using the promo to keep what they have.
And I do hope US offers one as well.
