What the poster does not mention is that this concerns becoming the owner of money oneself. Clearly, this is not what Ajahn Brahm is doing.
The 10 points discussed at the Second Council included accepting money "for the Sangha," not for one's personal needs.
Whether, its for one's own needs, or for the Sangha's needs, asking for monetary donations is not allowable. If an invitation is made, one can say what the Sangha needs.
I don't think this would apply to urging people to donate to, e.g. victims of a cyclone or an earthquake, because it is neither for oneself, nor for the Sangha. Still, putting conditions on such donations, saying, “If you donate $100 to the relief fund I will give a talk would still be unsuitable for a monk.”
This is not going to cause the demise of the Buddhasāsana, but its worth reminding people that donations and teachings must both be given with no strings attached.
