Can't speak for this particular team, but a submission for a competition is usually done on the last minute, so it's highly unlikely that _this_ algorithm is part of a product like Oxford API already. But a predecessor might, and it might get integrated over time. A research prototype usually requires a lot of duct tape to work. Productization usually requires a different mindset (i.e. an engineering rather than a research team) who care more about things like test coverage, distribution, (time) performance etc. So by definition, MSR is ahead of the curve, product teams are on the curve.
