Yeah,but Chinese firms are also investing in manufacturing and transport in other countries,as part of the BRI. This involves countries like Greece,Serbia,parts of Africa,etc.
Also,companies like Samsung,etc get state backing too in the form of big contracts awarded to them by the South Korean government. Apple,also spends very little of its money on R and D,considering how much it has,and US firms do get help in terms of preferential tax breaks,employment laws which favour them,etc.
You are right on Samsung, they also past on the cost to their subsidiaries to make their margin look good, and they also not treating their workers well too.
For BRI it does help some countries but I can say it is also a financial black hole for some countries and Chinese companies, debts are too big to pay back base on the return from projects and it is normal for Chinese companies (usually state owned) to take on contracts even at a loss. I am sure we will see some projects cancel and a lot of quality problems.
It is normal for firms getting support from government because R&D cost a lot and many projects ended up with zero return, without support we will see more short term gains instead of long term plans. But it is not the same when chinese companies get backing from government, it is hard to explain.
For games and others like Intel/Apple, we can choose what to buy, I never own an Apple product because I think they are over priced and I will go for AMD for my next PC. And don't buy games if publishers don't care their customer, no one put a gun on us to buy them.
