If the majority of your sales are intended for businesses that plan to constantly buy new laptops, it makes perfect engineering sense to just solder the ram to reduce costs. You also have to balance MTBF, the costs of rework, and the length of the warranty, these are all decisions engineers make when building products. You could make a laptop with components that should last 15 years, a modular design, and a plan to build replacements for years after but you'd end up with really expensive laptop that few would be interested in buying. Obviously engineers should strive for sustainability and not being hostile to diy repairs but I know who signs my paycheck and it's not XPS or Thinkpad enthusiasts on the internet.
