Probably they depend on some "obscure" contactor which is one of the ODMs here: https://en.wikipedia.org/wiki/List_of_laptop_brands_and_manu... .

Intel / AMD and BIOS vendors simply do not expose their designs to everyone. So you have to go through an ODM to have an Intel chip-based motherboard design. The silicon industry is completely rotten at this point. Framework could simply be too small to get access to secret sauce.
