A mysterious performance change of Fw190

The engine temperatures of the Fw190 are clearly wrong. I initially thought this was a bug, but it seems to be based on the bug report linked below. It is clearly dishonest and inappropriate to change an aircraft’s performance based solely on a single unsubstantiated bug report. Changes to performance require citation of sources, but this post only contains in-game screenshots. Furthermore, the performance changes do not seem to have been announced, at least as far as I can tell. At the very least, Gaijin should revert the engine performance to what it was previously.
