ROI was never promised. Ethereum has always had a "Minimum Necessary Issuance" policy. Keeping issuance constant would be deviation from the policy, reducing it when possible is in line with the policy. From the docs:
> Ethereum's Monetary Policy is defined by the rewards that are paid out by the protocol at any given time. Ethereum's current yearly network issuance is approximately 4.5% with 2 Ether per block and an additional 1.75 Ether per uncle block (plus fees) being rewarded to miners.
> Ethereum does not have a fixed supply because a fixed supply would also require a fixed security budget for the Ethereum network. Rather than arbitrarily fix Ethereum's security, Ethereum's monetary policy is best described as "minimum issuance to secure the network".
> Ethereum has had a history of reducing issuance to these estimated minimums and the network has never increased issuance. The move to proof-of-stake is also part of Ethereum's effort to reduce issuance to minimum amounts without sacrificing security.
