It violates the prime directive: thou shalt not centralize a decentralized currency, it was formed without a discussion first, it's initial leadership was not representative of the community but representative of business instead
Problems posed by this idea:
1) What happens if you attack TBF and Gavin gets mad and goes and becomes an amateur golfer instead. Bitcoin still needs more hard forks before it's ready to run unattended for years/decades, and there's not many people who can easily create this consensus in a timely manner. Even if you don't like TBF, it will probably do more harm than good attacking them, at least until every big fork is in the past. Standard game theory, you're committing suicide to try and make a point for no gain.
2) You can simply not donate if you don't want to, then you don't lose anything.
3) If you plan to attack TBF, can you pick a less retarded date than the same week of MtGox.
