I agree, Lyft should have the decency to inform bike angels of this change and explain it. The fact no advanced notification was given implies they either have a terrible communication process (or none at all) or they purposefully decided to roll this change out without any heads-up to existing bike angels which shows how little they care about this program.
Furthermore, here's the reply I received when asking if they'd honor my most recent $200 point redemption:
We regularly review the program’s reward offerings to ensure the health and fairness of the program. Bike Angels rewards are being/were updated to align with the spirit of the program.
They lowered the top reward "to align with the spirit of the program".
