There are two questions about the CCP and spyware: is it technically possible and do they have the political will to do it?
I don't think the CCP is putting spyware into the iPhone because it's only barely technically possible and they don't have the will to risk it. Getting caught with your hand in the cookie jar there would be the end of their whole economic strategy.
Would the CCP put spyware into Tik Tok? It's trivially possible, and the will is absolutely there. I would be more surprised if it were somehow proved that they weren't interfering with Tik Tok on some level.
Would the CCP put spyware into 5G? AFAICT, it would be technically possible, and the payoff from it would be so huge that they might have the will for it, but it's a close thing. Hard to say definitively either way. I think the industrialized nations should make their own 5G, just so they're not shut out of a growth industry, but the spy thing is sort of a wild card that could be something or nothing.
