Calibre handles kindle too (if you already have that). You "obtain" the books one way or another, and calibre converts them to a proper format and copies them directly to your kindle (via the usb cable).

Pirated books have no DRM, usually come in an open .epub format, which can be converted to whatever your reader requires, and you end up actually owning them, even if amazon decides to abandon the kindle ecosystem.
