If your network relies on dedicated ASICs, you're not as prone to this sort of attacks -- assuming you're the largest coin relying on these ASICs.
If your network is ASIC resistant in the first place, you would not need to be worried about being prone to ASICs that have huge hash rates. Building a truly ASIC resistant blockchain has its merits because GPUs are more decentralized and easily accessible for regular people.
ASICs are machines driven by greed and deceit.
