You raise a very good point. When I first saw this announcement I thought it was a great deal for foreign founders. But as a US expat I know what a curse it is to be a "US taxpayer". Foreign founders who end up being US taxpayers without planning for the consequences could suffer greatly. That scenario of your home bank closing your account is very real in countries that refuse to submit to the FATCA reporting requirements.
