I find it very unlikely that someone would get their house raided because of a "tax dispute." When I hear the word "dispute", I tend to assume that Wright was probably discussing his taxes with government officials, so that they don't accidentally charge him more tax money than they are supposed to. If he had simply "refused" to pay his taxes, that would be different. I'll bet the government will continue to gather evidence on him, before charging him with bogus terrorism charges. After all, he's made it easier for "terrorists" and other "criminals" to exchange money quickly and anonymously.
Let this be a lesson for all you non-corporate innovators out there: If you wish to create new and exciting technologies, use privacy-friendly services such as VPNs or TOR. Otherwise your government will hunt you down for obviously false reasons.
