They are fighting DRM by sending Nintendo... bricks?
Wearing pink shirts wont get Bush thrown in jail. Wearing teabags off your hat wont get Obama impeached. And sending bricks will not get DRM removed. Protest culture in America is a hobby and will not be taken seriously, as a result.
You want to stop DRM, you have to stop buying things that have it. Most people will not consider it enough of a deterrent not to, neither will most consumers even know it exists.
HTC removed locked bootloaders because a large number of power users decried it, along with a large number of competitors offering similar devices. Nintendo is the only game in town when it comes to Mario. It's great to send in emails complaining about it, but the only thing that's going to stop them from putting DRM out is a necessary public outcry (not going to happen - you need every 6 year old to care), or just them just figuring out the futility of DRM (which i'm not sure the statistics on).
