By selling iMacs, Apple are not *forcing* people to use an "all in one" computer. They are a contributing one option in a wider marketplace.

By offering a comprehesively anonymous network, DRK is not *forcing* anyone to use anonymous transactions. Likeways, they are offering *one* distinct type of product in a diverse marketplace.

Those arguments would only apply if DRK was the only crypto around. It isn't so they can't be accused of not offering choice when in fact that's exactly what they are doing within the wider marketplace.
