wasei-eigo (Japanese-coined English), from position talk
You need to be careful not to be misled by analysts' self-serving talk.
self-serving statement; talk that benefits one's own position
Generalized use: any statement or opinion that is clearly intended to benefit the speaker's own interests or stance, not necessarily financial.
