Industry standard is about 10 BPS for affinity programs and a bounty for acquiring customers for the bank. No rewards program might make this one higher, maybe 70-110 but none more.

A better plan if you wanted to support Linux would be 2% cashback card that you donate all rewards to Linux.

A an even better plant would be for the issuer to give 2% to the Linux Foundation (or any other non-profit of choice or even a mix), without making the merchant pay for it. The issuers are awash in money.
