I've been active in their Discord server for a year or two now and have monitored their rewards evolution and people's opinions thereof. It seems like people don't read their emails with program updates or maybe it's going to Junk Mail. 

They communicated all the changes about spin rewards and ACH rewards weeks in advance, but many people still seemingly caught by surprise. 

I understand people don't like losing the amount of "free" sats they were able to get before, but so much has changed. Given the changes with the global economy (i.e. rates) it's not surprising that they can't sustain the generous rewards, not to mention it's rewards on a DEBIT product, which is much different from CREDIT products. 

They have matured and adapted to the environment and their primary users: people who want to get on zero (fiat), a bridge between fiat and Bitcoin. To those who use it as their primary spending account the ACH rewards system is a net positive.  It's a Loyalty rewards system. 

It's not for everyone, and for those who are rewards maxis/optimizers who have access to other credit products with 5% cash back and can pay off their balance every month, good form them, but not everyone has access to those products.
