Bread, which is a Bitcoin wallet, will let customers purchase Bitcoin through credit cards and have the Bitcoins deposited into their Bread wallet following their partner integration with Simplex.

and watch all the chargeback scammers abuse that, and then after a while see bread/simplex remove that 'feature'.

haven't they realised the reasons most services don't offer credit card purchases. anyway goodluck to their profit/bottom line

This is only the matter of the margin per purchase, if they make the customers pay a margin that is high enough to cover the chargebacks (and not all of the credit card holders will start a chargeback after the purchase) they can make profit at the end. They can also ban their customers from paying with credit card after the first charegeback. Also, they can make a limit for the credit card purchases to maximize the possible loss of the chargebacks.
Of course, they can't apply a really high margin because in that case the price won't be acceptable for the customers, so it's not easy to plan and to calculate.
