Vendors remove local device control

Amazon removed Alexa voice control for the 3.5mm auxiliary input on older Echo speakers, so wired audio can no longer be controlled by voice even though app controls remain. The company offered no public explanation when queried. The change highlights how manufacturers can quietly take away features from devices already in customers' hands. — Signals a growing trend where cloud/platform dependency enables vendors to withdraw local device functionality, influencing debates on consumer rights, device sovereignty, and regulatory remedies.
