Yeah, that's also what should be the worry. Obviously ideally , it would have been better to have one or two standard system and scale it up. That way they can better compete globally due to their wide adoption, vast data usage and scale.
However, we dont live in an ideal world, so I think we are likely to see many more such supernodes system by other companies this coming years. Remains to be seen how this will end up and if it will be the norm for every major company to build their own.
