I don't think this is Apple's plan. It's more that Apple has been developing in house modem technology for years (they bought Intel's modem division in 2019) because they are reliant on Qualcomm for them in iPhones. Once they have the capacity to build great modems and add it to their vertical integration/SoC process, it's another no brainer thing to add that makes their laptops best in class. However, if it gets picked up by other tech companies then yes, expect your device to be always connected, even if it's against your will.
