It's totally reasonable to lament duplicated effort, but it's worth pointing out that this particular attempt is from a company[0] whose business is Qt consulting - so it's easy to imagine that they might succeed (due to expertise, size, and motivation) where others have not.
The post also explains why they started from scratch vs. existing approaches - I'm not qualified to evaluate the claims, but I think they deserve some credit for explicitly talking through their reasons.
