The profitability there is deceptive. Many of those coins do not have the volume to support large scale ASIC use. Monero, perhaps ETN and Sumo might support some but the rest could not.
There are only 2 coins that can even remotely support the hashrate these things can muster. Those two are Monero (which already made it clear they're forking against this ASIC) and ETN (not sure if they're going to fork against or not). Every single other coin can barely break 1 BTC daily volume. It's a joke. You're legit stranded with an ASIC that has just about the most limited number of coins algorithm wise.
I wouldn't say it's the most limited, but it certainly isn't the most profitable. My guess is that it was just easier to engineer an ASIC for than anything else that is semi-popular. I certainly hope that most coins' devs have at least some common sense and move to another algorithm.
