While the First Sale Doctrine applies in principle to software, in practice nowadays it's very difficult to exercise that right. A lot of it is subscription-based, and reselling your subscription is pointless. Other stuff is DRM-encumbered, and/or tied to an online account in some form, so you can't really resell it successfully, at least not without breaking the DRM, which is in violation of a different law. And the manufacturer would claim that you've licensed the software, not actually bought it, anyway.

Gross.
