To be fair, it's hard to know how satoshi feels about what's going on with bitcoin. Although bitcoin has deviated from its original purpose as an investment asset and is increasingly regulated and controlled by governments. But that inadvertently helped him become one of the richest billionaires in the world. If I remember correctly his net worth is over $100 billion as he is said to hold over 1 million BTC, and I don't think anyone would be sad or angry about owning such a huge fortune.
Furthermore, even though it has strayed from its original purpose, bitcoin still retains its decentralized nature, so why should he be angry when bitcoin's core value remains the same?
It is not clear how Satoshi Nakamoto feels about changes to Bitcoin, although, most probably, these changes have mixed feelings to them. Although Bitcoin was originally designed as straightforward digital cash, it currently registers as more speculative investment given that it has high degree of price fluctuations and sluggish transactions. Trend towards government regulation also contradicts its initial purpose, that of being entirely unregulated system. However, at same time, immense wealth that Satoshi earned through stockpiling Bitcoin would be difficult to feel bad about as evidence of project financial success. Most importantly, Bitcoin still retains its essence of decentralization that is. Nobody and no government can control it. This is main characteristic that would be in line with original vision and witnessing technology succeed and transform financial world would be source of pride.
