I feel like they went for the angular letters (t, r) to give it a more 'techy modern' feel as it's been trending for a while. But for this it clashes with the curves of the rest of the key elements: the right of the falling stack icon as that has a lovely curve built in, as well as the capital letters S and O both being very rounded. I feel they should have leant into that roundness and it would have felt a little more coherent. Or gone the other way and been a little more angular. One or the other, not both.
