@KyokiKafuka @ayachan I wouldn't be surprised if Nintendo had firmware that caused Switches to shut down when connected to third-party docks, but I think it's much more likely that the third-party docks are reverse-engineered junk that breaks the hardware to which it's connected.
Yes, Nintendo should be obligated to publish specifications for every console it sells so that others can design compatible peripherals. However, Best Buy's "Insignia" line is overpriced shit that only idiots buy.
