That's been the case for a LONG time. If you have below a certain amount of sats in your account, they drop the lowest reward by half. Which, at the current BTC price, the normal reward is 2, but drop that by half, you get 1.
The base reward would be less that $0.002 of BTC (which is currently 2 sat) if you have a low ratio of total wager amount to free winnings. I don't think your base reward would decrease to less than $0.002 just because you have low balance.
Read TheQuin's post for more information.
You are getting less than the actual base reward. Generally, Freebitco reduce the faucet base reward for those users who claim the faucet always to gather free BTC.
For clarity, it isn't "users who claim the faucet always" but rather users with a low ratio of wagering to free winnings that get the low wagering reduction.
