ASIC manufacturers do not care about cryptocurrencies technology, neither markets, the only one concern of these enterprises it is to make money. They do not care if they destroys coins, algos, markets. They develop ASIC devices, use it in secrecy (For community, for Devs no sometimes), and finally sold these devices as "new", but then and only after then, mine coins with it, take huge profit (Destroying coins, markets), also then recover the units cost and make another additional profit, with fools that buy these ASIC, but when start to mining it is too late to make profit, even no factible.

The problems with ASICs, aint ASICs, it is the monopoly behind it.
