Can you elaborate? If the ETF is tracking with very positive correlation, and spreads are reasonable, where's the problem?
These ETFs just started trading. Keep an eye on these, and if they steadily increase in average daily volume then the spreads should tighten. With a little time they may be worth trading if it is free.
Likely just a "loss leader"... we'll see if those ETFs pick up in volume to be competitor to established ones.
