As someone who was personally a victim of the 1-2 punch of vulnerable HW and unquestionable malware that took advantage of said vulnerability from the same vendor (and I have the pcaps to prove it), I have sworn off CN garbage forever, I don't care if I have to pay 3x the price.
No one stops you from doing so, just know you will probably be part of a botnet sooner or later.
If you have proof, then why wouldn't you name and shame the vendor in question, or at least be less vague about what kind of product you're talking about? Talking about how you determined that you were being attacked through a combination of hardware and software vulnerabilities would be way more interesting and appropriate for this forum than generic anti-China complaints.
