I mean Valk got the outladner to train with them. Besides it seems marr and satele drew their conclusions from sesnsing valk in the outlander and/or the empire of zakuul's force philosophy.
I'll elaborate on the latter. The supposedly expanded philosophy of zakuul which allows them to wield the force differently is that they draw power from their loyalty to Valkorian. In other words, looking at the events of the game as a whole, Valk basically created this philosophy based around servitude to himself and then took advantage of the enslaved civilization in a convoluted plot to take control of the entire galaxy. While the philosophy of the fckers he duped may be different, Valk's actions work perfectly in line with the philosophy of the sith/darkside.
2. it's oerfectly plausible they're falling valk's bs here when you consider that they're also molding the outlander exactly into what valk wants him to be as he plots for galactic control, an objective which is as sith as anything.
it is, because valk's factually a sith, and no objective statements actually contradict that, not to mention valk's ending objective is exactly the same as your typical sith lord.
