Obviously less options isn't better in all circumstances. When of the options happens to be predatory then yes obviously it is better to not allow such a thing.

Imagine you have two options. You can either pay a one time fee of $50 or you can borrow the $50 and pay back $2 a month with 75% interest. Is allowing people the option to accidentally pay 5 times the amount something is valued better? Not that this situation is completely analogous to what is going on with Sync, but the point is to demonstrate that there exists a circumstance that less options is better for the consumer. Or at least a circumstance where having the only option has more integrity.

The best option I see for Sync that doesn't implement ads at all and thus being bad is to have a less featured version for free and then sell premium features. Or of course just sell the whole thing with no free version. There is also a the concept of a limited demo so you can try before you make your decision to purchase. There are so many things you can do that don't involve ads.
