I mean, no shit? Part of the Snowden leaks was information that the NSA had intercepted Cisco routers and backdoored them before they were shipped on to international customers. So, even without willing actions by US vendors, there is that to worry about. And the idea that a private company would install a backdoor for US Spy agencies in their infrastructure isn't new. The fact that any Chinese company is using US hardware/software just seems incredibly stupid. And no one should be using CheckPoint.

It's the same reason Huiwei was thrown out of US infrastructure. You cannot build trusted architecture with hardware/software from a nation which you know wants to hack you. I work for a US based company in cybersecurity, we treat WeChat as Chinese State spyware, because it is. We wouldn't consider a router or firewall from a Chinese based company and we treat any software from China with outright suspicion. Sure that all sucks and we may be missing out on some great stuff which isn't malicious. But, the risks far outweigh the costs. I'd expect my Chinese counterparts to be making the exact same risk calculation for US based tech.
