Lee Kuan Yew isn't anti CPC. If he were anti-China, he would have sided towards Taiwan.
He has to watch what he says. The future in Asia is linked to Chinese Ascendancy. If you want to thrive, its important to have a working relationship with Beijing. Even Taiwan, which has ideological odds with the Mainland, is more linked to China Mainland that the rest. It's the irony of it all, right? lol.
Singapore's success is dependent on a thriving relationship with China. Period.
