Alaska did exactly this in 2019. I had purchased discounted QF tickets 9 months before travel expecting to earn 100% of flown miles. Then 5 months later Alaska dropped the earning rate to 25%. I wrote to Alaska twice asking for an adjustment for this (to me) retroactive change. Alaska refused twice.
