I can't speak for anyone else, but for me - I'd be asking why there is a large area impact on the radome but no damage at all to the pitot probes or what I assume is an AoA probe immediately behind the damage.
My first thought too.

There are what appear to be slashes from a prop at the upper part of the impact zone, but that would need a metal prop to achieve (the nylon props of a multicopter wouldn't even scratch the paint) so that rules out a "drone".
And for the props to make the slashes the motors would all have to have been twisted 90degree (*exactly*) by the first impact on the nose. Otherwise there should be circular marks along each track.

Not all multirotors have plastic props, one in which I have a half share has carbon-fibre -- spinning at 7000rpm. I believe that one of those could get through a relatively thin glass-fibre radome, but three cannot touch it simultanously and leave just a straight slash. This is all in the wrong plane.
