You're dismissing the parent argument merely based on a narrow interpretation of the word complicity. The way they use it is common and correct in English language. All it needs is to aid the wrongdoing in some manner. That's exactly what you do when you choose to support and lend credence to Apple's flawed arguments on safety and thus blunt the opposition to their hostile practices. This is significant because Apple has been forced on occasions to backtrack on bad decisions in the face of public backlash. (Anybody remember their plan to scan all photos in the phone for CSAM?)
Now even if you want to go the pedantic or legal route, the meaning of complicity changes according to jurisdictions. Many legal jurisdictions consider interference in the opposition to a crime or even silence in the face of a crime to be complicity if you had sufficient knowledge about wrongdoer's intent. In this particular case, people had been warning for decades of this exact outcome, down to the details of the headline.
You could argue that this is policing of thought and opinion. Obviously, we're talking about moral responsibility here, which is just another opinion too as far as consequences are considered. (Except in cases of astroturfing and sock puppeting where the complicity is more direct. But we will ignore that possibility for now.)
