The poor boy is getting his science awfully confused
The transfer of angular momentum from the Sun to Jupiter was a lot more involved than just magnetohydrodynamic breaking, although that played a major part in the loss of the Sun's angular momentum, very early on. It's also a lot more involved than the Sun stripping electrons off its gases and expelling the ionised gas as solar wind, though that is also a part of the process. It has very much to do with the way these two planets formed and interacted with one another, and the Sun's magnetic field and other interactions as well. Just because Jupiter has most of the Solar System's angular momentum doesn't, by definition, make it a star or anything else other than a planet.
This is precisely a case of where people with an incomplete and inaccurate knowledge of what they're talking about can get things quite wrong and end up misinforming and confusing other people, who don't know.
