Every thing the guy said was in fact, fact, aside from the Revan > DE Palpatine. Revan did turn his remnant of the Jedi/Republic forces into Sith, the Jedi by the use of the battle of Malachor V by summoning DS energy from the planet and using it to dominate the will of the Jedi who were too frenzied in the battle to resist the lure of the Dark Side
This process of "turning" Jedi into SITH ASSASSINS continued even as the Jedi Council hailed Revan as a hero, as he lead the Republic forces to victory over the Mandalorians in the skies above Malachor V, and forces them to surrender. Revan is able to draw upon the dark side energies of the planet below and use it during the battle...more and more Jedi, unable to ignore the power emanating from the planet below, become corrupted by its influence. - The Chronicles The Proving Grounds
Now as for the rest of the fleet, Revan spread Sith teachings through the ranks as Atton makes mention of, and all of the remaining were completely loyal to Revan as Atton again says.
Its also been speculated that Revan could form mass bonds like the Exile could that could influence Jedi and Commoner alike
Evidence:
Mical (The Diciple) says that Revan studied the bonding ability deeply before he left for the wars.
HK - 47 again confirms that Revan did infact study this ability and was interested in the Exile for the very fact that she could make these bonds
Kreia brings up the point when talking with the Exile about Revan the dialog is:
"When Revan spoke with conviction, there was little one could do to resist him." - The Exile
"Ah but to make officers betray their loyalties, bombard their homes...strong words indeed." - Kreia
Kreia also says that this method of converting people was "Revans way" then she goes on to mention that Revan knew the strength in creating wounds in the force and how they could be used to turn people.
So yeah he's pretty right.
