That will likely be a part of it. Though finding pockets to go after may be difficult as well: hardware and software components are already modular, there is the developer, the manufacturer, and often a "brand" who effectively purchases the tech and tosses a logo on it (Apple is an exception to this rule). To say nothing of transnational jurisdictions.

The complexity problem extends to the legal side as well. Much as I think liability could help, it's going to be hard to apply, particularly with lay attorneys, judges, and juries.
