Joe Sugg may have been seen as the "nice young man" but his dancing was nowhere near the other "nice young men" who made it to the final (Hamza, Jay, Joe McFadden, Harry, Louis, HRVY, John) so I did find his appeal baffling. The YouTube fanbase for sure boosted him but won't have been the sole reason he was there.
IMO, he'd have got lost in the shuffle and left a lot earlier if there was a really good male contestant that year with voter appeal. The men that year were pretty bad - Charles was great at latin but struggled at ballroom, Danny JJ was limited by age and didn't mesh with Amy and then Lee, Seann, Dr. Ranj & Graeme didn't stand a chance at the final.
