Nostalgia-bait isn't going to make addictive social media go away, and these devices will probably end up with easily foiled workarounds to get to those services anyway.
Also, did Commodore even used to make flip phones? I had a legendary indestructible Nokia brick, Motorola flip phones, and one really shitty Samsung flip phone. I'd feel nostalgic for something from them if it had the same design (but not the shitty Samsung phone), not for a pseudo-oldschool actually-it's-just-Android-but-less-functional phone.
