This issue is a bit more nuanced than this, but don't get me wrong... I see your point.
According to transfermarkt, in this window:
Arrivals: Sum: 45,45 Mill. €
Departures: Sum: 11,50 Mill. €
Last offseason Belotti could have been sold for a truckload of cash, but he was kept. At this point in time, that decision can be mocked, but it would be difficult to argue that it was a decision that would have been made if solely looking at profit margins. Even if he had a very good season in 17-18, it was always going to be unlikely that his value would have been greater than it was prior to the season.
Last seasons wage difference between Torino and Juve:
Torino: 46 €
Juve: 164 €
It's a silly argument to say Torino should be taking too many points away from Juve... This isn't the Samp-Genoa rivalry. Supporting Torino is either a passion, or possibly, one is trying to support an intelligently run club that can take a reasoned shot at European competitions every few years. Juve doesn't need to be run well, they can just outspend their mistakes.
Sure, it would be exciting to see some names get signed, but Torino's wage bill sat at 7th highest in Serie A last season. If they were to focus on competing with Juve (who spends nearly 4x as much), then FFP would rule the club out of Europe even if they did qualify.
