Apple products are used globally, so even if they do restrict their spying efforts externally, the ability to hack Apple products is aligned with those efforts.
They should also absolutely be looking for vulnerabilities in Huawei products. They should be looking for them in any product with significant market share. But there's no reason to think they can't do both.
All that aside: Theres a social credit system with Tinder? Am I reading you correct? Tell me more! That sounds way more interesting...
Apple sales in China are ~10% of the market and falling.
In the US (especially high value targets) are ~50% or higher. That's not a good ratio for the US. I suspect the numbers for Russia are more similar to China. Targeting your own people (and not trying to secure the system) isn't a good strategic plan.
Thought experiment: You're a chinese spy. Your enemy is pouring tonnes of effort into hacking the phones made by your own country, but have chosen to put zero effort into hacking those made by theirs.
Which phone do you use?
Meanwhile, your own people are good at hacking both American and Chinese phones.
So in this scenario, the USA's decision to not try to hack products made by American companies leaves them at a decided disadvantage to China's decision to hack all of them.
Hack the NSO group (or any of your adversaries/allies) and use their zero days... likely a lot cheaper than developing your own or creating new ones for other people to hack and use against you. If nobody else has any, you're not behind :^)
