Crow damaging the lines in front of our building?

I asked about this on Reddit and included a picture. According to the electrical enthusiasts over there the thing that's being punished by the crows is a splice cover for non-electrical cables.

Anyway this crow is obsessed with it and today I saw it was pulling on what looked like a little bit of fabric from the middle of this cover where the lines go into it.

Is this a potential problem?
