Well first, over time they will all sync whether you are trying to or not. All it takes is 1 day of too-busy real life and everything is synced. Or server maintenance/problems not allowing login. Or simply the ebb and flow from the 24-hour drift. It takes a very serious and dedicated player to prevent sync from happening over not too long of time.

Now, as to the "problem" of leveling GB early, I've heard it said elsewhere of people intentionally "attacking" players in the form of preventing double-dipping by leveling their GB. In a game that allows plundering and other direct pvp attacks, this is as valid as any other. Anything you do to "fix" this takes away your opponents right to cause it.
Frankly, as much as I like to maximize my return in games like this one, the fretting over double-dipping is more than I'm willing to worry about. Is a 10 FP loss in a day noticeable? Absolutely. Is that same 10 FP loss noticeable over the time scale of a week, a month, a year? Not so much. The loss is a one-time hit. The GB boost is a continual gain. All one-time effects are negligible in the long run. If you are leveling GBs fast enough that you are losing 10 FP every single day from loss of double-dipping then you are making so many FP that even 10 a day is a fairly negligible amount.
None of this even takes into account whether or not one ever accidentally overlooks a GB that is ready to level and doesn't double collect at first opportunity. Then one can begin to actually lose out on gains because it didn't get auto-leveled for them.
Either way, can it be frustrating to feel like you could have had more? Sure. Should you berate or de-friend someone over it? I suppose that's up to you. Some people will continue to do it because they want to attack you, some because they don't know better, and some because it's too much hassle for them to bother. The third group is the one you have the best chance of fixing. If you want to take a stance, try to get Inno to actually allow typing in a number of FP to donate. It's so much easier to click that donate all button then it is to click donate 1 over and over to get the exact amount. (not to mention lag can play a big trick there as the game isn't caught up with itself and so click 1 last time only to eventually see 2 go in)
