There is a technical reason for integrating the RAM into the CPU package. Having it very close coupled does allow for very tight timing. Some other manufacturers solder in RAM too, particularly on AMD laptops where SO-DIMM sockets would limit the maximum RAM speed and thus the performance of the CPU as well. The performance hit isn't huge, in fact in workstation/productivity tasks it's basically zero, but in synthetic benchmarks and a few games it is noticeable.
Apple's Mx chips need a lot of memory bandwidth and as low latency as possible. Partly because they share it with the GPU, and partly because the ARM architecture just needs more than AMD64.
But of course it was a choice for Apple to do it that way. They could have used a different architecture, the could have traded some performance for RAM sockets, or they could have switched to AMD whose CPUs are better than Intel's.
And there is no excuse for soldered in SSDs.
