After re-reading the article, it seems that the Chinese owned company mentioned (G&E) is just buying time on the MW stations -- except they are buying all of the time, instead of just an hour here and there like you see on many brokered MW and SW U.S. stations.
Sometimes on good DX nights I can hear the station in Portland, Oregon, KXPD. Mostly what I've heard (when I've actually heard the station) is the same CRI English programming I've heard on SW.
I myself am not bothered by it. China and the U.S. have to figure out how to get along. China is one of our largest trading partners and apparently own a lot of U.S. debt. It may not be a pretty relationship, but it seems like goodwill between both countries needs to increase, not decrease.
And if these stations are putting out 'propaganda' it can't be any worse than the stuff that flies across the radio and TV airwaves here in the U.S. each election season.
