Yet, Macbooks had upgradeable ram and storage upto about 12 or 13 years ago.

Yeah I bought some extra RAM for my old macbook (which wasn't old at the time).

It was even easy to do it, no need to take it all apart. There was a lid behind the battery.

Remember that for people who used computers in that period, opening a computer to replace a component was a completely normal operation.
