Did Russia “betray” India by selling BrahMos technology to China to develop CX-1?

Judging by the photos, yes, the missiles look similar. It was also said that the missiles have a similar maximum speed and flying range, but both these characteristics can be due to the Missile Technology Control Regime, because in absence of such "guidelines", every nation would want to increase the range and speed of her missiles. In short, these characteristics should not be used to make a judgment about the missiles.
Similar thoughts were also expressed by A Sivathanu Pillai, who is founder-CEO and Managing Director of the BrahMos Aerospace Private Limited.
He also added that both the missiles have different engines, different propulsion systems and Brahmos has higher range at lower altitude, but lower speed at higher altitudes.
One way I see it is that it can be just a mind game by Chinese who might try to create distrust within Indo-Russian relations (by making both parties point fingers at each other) or show their skills in cyber espionage. We'll never know for sure.
It can also be argued that China attempted to make a copy of Brahmos for export markets. But then, it is always easy to measure everything accurately with a scale and copy-paste. It is difficult to replicate what's inside.
