Either people can't read or they are just living in their own world.
The article never says the USN is reducing their total buy, much less giving up on the aircraft. It simply says that, instead of getting 54 F-35Cs by 2020, the USN wants to get 38 by 2020. So they reduce the LRIP a little.
No mention is made of reducing buys after 2020, when full-rate production is to begin.
However, this is enough to trigger the "OH MY G@D THE SKY IS FALLING AND THE F-35C IS DOOMED FOREVER" brigade to hare off in full cry.
