From the comments: Actually, I'm surprised they haven't tried making their own computers to scale until now. It's the age-old management dilemma: Do I Buy-Built? That's a faster, easier, cheaper option. But it leaves me at the mercy of the manufacturer. Or do I build my own? That'll be the slower, more difficult, more expensive option. But it also makes me completely independent of outside manufacturers. Most managers and companies tend to buy-built because it's more cost-effective. It's only when they don't trust the outside manufacturers that they go to the expense of 'rolling their own'. Both China and Russia have 'bought-built' so far, but the US semiconductor sanctions on China will mean that China will 'build their own', and then Russia will very likely prefer to buy Chinese rather than Western semiconductors. That'll be quite a market-hit on US semiconductor makers.
