It isn't some giant secret; they are super fast on the straights so followers with drs can't get alongside, and are "fast enough" (but slow comparatively) in the corners that nobody can get past them.
We see this pattern from them in every race; they always lead a long drs train, with the car in front of them tens of seconds ahead.
It they had just kept their mouths shut and taken their lumps, it would have blown over by now.
But the ego on Spez is apparently incapable of tolerating the fact that someone on the internet might disagree with him, so he keeps doubling down and making everything exponentially worse. To the point where people like me, who couldn't give two bits about 3rd party Reddit apps or API or pricing, are so disgusted by their behavior that they look for alternatives.
