A similar argument could be made about software running on servers, and circa that same time as that quote on microwave ovens I believe Stallman in fact took the position that servers did not raise such issues either.
He's changed his mind about servers since then, so I wonder if he also has since changed his mind on devices?
IIRC he's fine with servers that are simply used to publish information but he does not use SaaS type websites unless they are free software and he has control of his data.
