While it is true Apple sources most of the components in Macs from China that does not mean they are garbage. Your comments feel Sino phobic and really aren't needed. Most of the most expensive high tech equipment is made in China. China can make the very best of anything as they have now a strong, mature, manufacturing base as well as tons of scientist and engineers. Most Windows laptops are assembled if not completely made in China. Quality depends on price. If you pay enough anything made from China will be as good or better than anything else.
That all being said the BOE panels that Apple is using are obviously cheaper and of a lower quality than manufacturer's like LG and Samsung BUT Apple is investing in BOE and helping them with their designs and tech so they can get better panels, cheaper but it takes time for BOE to reach parity with LG and Samsung and they are not there yet.
Personally I have moved away from Apple products due to where they manufacture and their close ties with the CCP. I feel like Tim Cook is all in on China despite the fact the Chinese are direct competitors to Apple and want to replace Apple with Huawei as soon as they can. Most Windows OEM's may use multiple factories including Chinese ones and source components from all over the world. They are not as invested in China or as vulnerable as Apple. If you don't want a computer at least made in part in China you don't have a lot of choices. You can get a Samsung GalaxyBook made in Vietnam but how much better is Vietnam over China when they are both Communist countries?
That all being said, as others have stated the display tech has changed with M series processors and how they display as well as 8 bit and dithering on the IPS screens. So PWM has not changed at all in M3 series laptops. Unfortunately for those who are sensitive Apple doesn't seem to care?
Other companies like Asus use software to help with flicker on their Oled screens and many other's do to. PWM has changed on Samsung phones as well.
If you were sensitive to any MacBook screen on M2 or higher than nothing has yet changed on the screens so you would likely still be sensitive.
Sourcing assembly services and simple manufactured components from China is okay, but they completely fall behind competing countries in more sophisticated high-end components such as displays, memory, logic fab, etc.
The only complex tech they lead in is LFP batteries, and that was due to flagrant IP infringement. While the rest of the world was waiting for the LFP patents to expire, China ignored them and manufactured + sold them domestically for 2 decades, giving them a large lead over other countries.
There is no reason for Apple to go with China for any complex components such as the display except to cut costs. This issue could’ve been 99% mitigated if they went with OLED like some Windows manufacurers did.
As for BOE, the only reason why they’re still competitive somewhat in OLED is because of blatant tech theft. Says a lot about Apple that they still work with them.
I agree with you that Apple’s pandering to China is spineless, unethical and sickening. All that moral superiority and virtue signaling only applies to inconsequential issues like gender identity. However, that arrogant self-righteous attitude goes right out the window when it comes to sales.
