Umm that intel processor is the weakest of the bunch

Brother, what Intel processor are you talking about? They sell the latest gen of processors, which are the best you can buy.

guarantee you that they will be out of business within 5 years.

LOL based on what? They sell more computers than they can produce.

you literally can get an equivalent laptop from another manufacturer with new RAM, SSD and the screen, battery and everything else, and still use the old laptop

For a lot more money, yes. I don't think you get it. You can just upgrade the motherboard. You don't need to replace anything else. You can upgrade the display, you can upgrade the RAM, you can actually repair the battery, the keyboard, the trackpad, etc. etc.

the alternative would be soldered on RAM

...nope? Not correct. They can continue using regular old SODIMM RAM like they already are in the FW13. Don't know where you're getting this from.
