Why did Russia shoot down a satellite in a mysterious orbit?

As reported by the Ministry of Defense of the Russian Federation
(https://bit.ly/3CzYquS), on November 15, 2021, the Ministry of
Defense successfully conducted a test that hit the inoperative
Russian Tselina-D spacecraft that had been at orbit since 1982.
In an interview with Mark Feigen (https://bit.ly/3qSpOSJ),
astronautics expert Alexander Morozov suggested that the strange
altitude (around 400 km) at which the satellite was shot down was
not chosen by chance. It is at this altitude that, in addition to the
ISS, "Star link" satellites fly, spying on the entire planet. Thus,
having created a cloud of debris, the Russian authorities did not
give Elon Musk the opportunity to fulfill the plans of the "world
behind the scenes" regarding total espionage.
The Russian authorities have kept their promise. Back on August 16,
2019 (https://bit.ly/3nzfm0g), a Defense Ministry official said:
"The emergence of the so-called universal Internet uncontrolled by
the authorities is absolutely unacceptable for the Russian state."
Thus, the Russian regime was drawn into a direct conflict with the
"Committee of 300" and its henchmen from the "world behind the
scenes."
