I would have been perfectly fine with Chrome alerting me to that fact and providing a "click here to continue anyway" link, but that seems to no longer be an option. FWIW, Safari did the exact same thing. Only Firefox gave me the "I promise that's really what I want to do step aside plz" button I needed.
Still sucks for consumer grade stuff. I'm surprised your router offers SSL at all though.
That's like shutting down all roads because some drivers break the speed limit. If Google isn't taking collateral damage into their decisions that impact everyone, they need to stop controlling the web.
That being said, the real fault in that incident is ICANN selling .dev in the first place. They should've been well aware of it's common use, and opted not to sell it.
I think .dev was just too much money for ICANN to say no.
Of course, it looks like ICANN may have gotten screwed, because Amazon and Google appear to have privately arranged to figure out who was going for which TLDs: https://icannwiki.org/.dev
