Feitian announced a few months back that all of their u2f products were using their normal javacard chips.. (Some of the low end older ones were either different chips or could only ship permantly "personalized".)

Bulk orders of any recent feitian u2f should be able to ship with firmware you built yourself (probably with their SDK and help.) Effectively, that might mean very little since they probably can't support much more in combination with a u2f applet, but it would allow a vague statement like in the article and explain an avoidance of clarifying whether they support other pki or otp which is what distinguishes the high end tokens people like to talk about.
