In general tripod mounts aren't designed to be pulled from the bottom (they are designed to mount the camera and lens on tripod), so not sure if there would be any possibility to claim it is Olympus's fault if it fails from such usage. Some people refuse to use tripod mount straps for the same reason.

When the camera is on a tripod with a longish lens, the torque of the lens is pivoting around the front edge of the body, which levers the socket, i.e. pulls it from the bottom. The loads from the capture clip aren't much different - if anything, they're more benign because clips and slings aren't generally attached to a rigid body.

People say that tripod loads are small because they're static, but that's not really so. Mfg can't just design for the camera to sit quietly on a plate. People carry tripods around, they fall down, and things fall on them, yet most of the time the sockets don't break. So they must be designed with hefty safety margins.

It's looking like the safety margin isn't big enough this time.

The center of gravity of the lens/camera will not be right at the tip (keep in mind the camera, although light, still weighs 14.6 oz / 414g with the batteries) and the amount of forces actually pulling up on the socket is still going to be significantly less than having the full weight of the whole body and lens combo pulling on it.

Also as another pointed out, when lenses get big/heavier they come with a tripod foot you are supposed to use, exactly for this reason (so it doesn't stress the camera's tripod mount). I try browsing around and it seems once they reach past about 1.5 lbs they start coming with tripod foots.

With a capture clip or a tripod mount strap, I imagine you are unlikely to be swapping the attachment from the camera body to the tripod foot of the lens.
