It happened to Samsung before this, when it moved all of its smartphone production out of China in 2019, mainly to Vietnam and India. Samsung had its market share in China drop from 20% in 2013 to around 1% today. Apple is the next smartphone company who made the serious push to move its production and supply chains out from China. Namely to India, and Vietnam. Even more provocative was Apple's push to have India replace China as Apple's main manufacturing center. Because both the US and India are the most active nations in trying to sabotage China's economy.
So imagine one day where Apple makes its iPhones mainly in India, and then sells them in China. This, after unnecessarily dismantling its manufacturing center in China that was running so well. The made-in-India iPhones will be more expensive, lower quality, scarcer, and worse, it makes a mockery of China's relationship with Apple. So why should any Chinese put up with this nonsense? Giving business to people who are seeking to undermine China. Its Apple who unnecessarily provoked this, so they should feel the heat. Since India is more important to Apple than China, they should go and sell more iPhones there, and forget about Chinese business. The Chinese will have full justification to support their local smartphone brands over those untrustworthy and ungrateful foreign brands.
But China is moving on already. It is no longer just a cheap factory and big market for Apple and Samsung. It is becoming serious competition to them.
