Everything you are complaining about are standards. Without standards nothing would work together. New standards would mean billions in existing hardware no longer works. It would also mean any manufacturer trying a new standard wouldn't be able to sell its products to an existing install base. Perhaps a clean slate design would look very different but because the current standards still work there is no reason to change them.
Also, yes it's just you. But feel free to start a company making proprietary adapters. Perhaps you can find a niche.
