If you believe that splits cause customer confusion, and balkanization is unnecessary, then one way to help this problem is to use all your weight to ensure that BCH fails, not only to fix this split but also to demonstrate for any future splits that they will have little to gain.

Helping the split in any way (e.g. by making the split easier to use or by acknowledging it as a reasonable alternative) means facilitating future splits and future balkanization, driving down long term value of BTC.
