Its not radio emissions necessarily, but general EMI, which isn’t illegal. But we’re talking about such sensitive instruments looking for incredibly faint signals. While the noise from 1 satellite might be insignificant, the combined effects of 100,000+ of all the planned constellations is going to be brutal to the noise floor. It’s the same deal with optical astronomy. Bright spots are an issue, but they are also going to increase the general diffuse brightness (noise) of the night sky, which is already reaching ‘problem’ threshold with the current number of satellites.

Nobody’s dropping a MOAB on Moscow, because it’s dropped out the back of a C-130.
And even if they did it’s got less than 4% the yield of a B61, on it’s lowest setting, that fits inside an F-35. On it’s highest setting the B61 is 30,000 times more yield.
Conventional explosives are toys compared to nukes.
