We encountered already several kinked legs on 2 different Matrices.
These were caused by crashes, but also "just" rough landings, so I guess the one to blame is mostly ourselves.
However, the part that is broken, the plastic tube attached to the antenna (under the rotor) with the springy feet (which are in bad shape also btw) are meant to be easily replaced, as they can be screwed off.
The question would be where and when these become available as spare parts, as they are not on the DJI website yet.

I would check online dealers.  Several have Matrice parts.

For reference for future users, a "Landing Gear Kit" with four new legs is available at the DJI developer tools store. The legs are really easy to replace--unscrew the old on and screw the new one in.
