I am not suggesting Forward Error correction is a good idea on TCP. They put UDP and forward error correction together which is a good idea (see video/audio streaming over internet). The parent seemed to think they had reimplemented TCP badly, which they didn't, they implemented quite a different protocol which utilised forward error correction which was a good idea and something they would not have been able to do by building on vanilla TCP. So their prototcol probably ended up messier than it should of been but they were pioneers fixing problems as they cropped up so that's understandable.
