Desperation will ensure sales to the only customers (PC building enthusiasts) who will still care about traditional removable RAM.
Normals never install an OS, never open their computers, and never install internal hardware upgrades. People who do are "techno-divergent".
Apple demonstrates soldered RAM and storage are no barriers to consumer sales with zero need for a hobbyist market.
Ancient Slashdotters remember COAST (Cache On A STick) and why it went away.

Today we have ROAST (RAM On A STick) which only exists for customers who cannot afford to max out RAM on computer purchase, there being no (conventional user to whom computers are magic) downside to max RAM.
Being able to buy a PC with a cheap spinning rust hard drive and the least offered amount of RAM then binning those and maxing out with aftermarket parts (mostly Crucial RAM in my and many others case) was great while it lasted but the vast majority of PCs go from womb to tomb without upgrades and will in future.
