Yes the special dispensation to allow them to run with V10s was originally meant to ensure Minardi could afford to stay in the sport, and was made as a gesture of goodwill in some respect, knowing that Minardi couldn't afford to buy in someone elses V8, even less develop their own!
However since the team was bought out by Red Bull to become Scuderia Torro Rosso, the financial element was somewhat negated by the millions available to the team from the drinks company!
Hence some feel that they should no longer be allowed to use the V10, since they can plainly now afford the V8, and that their decision to continue with the V10 kind of runs against the spirit in which Minardi were given permission to use the V10 for this season only (it has a 16.7k rpm rev limit I believe, and a 76mm max diameter air intake, so its supposed to be less powerful, but its probably still a 'torqueyer' motor than the V8s, hence some feel it is a very strong engine, and should be restricted further to reduce performance still more so they are actually disadvantaged by it).
