It’s not the number of participating users that decreases the reward, but the number of committed ALGO, the reward is a fixed amount, it can go to a user who holds 4 billion ALGO and decides to freeze them for 3 months or to 4 million users each blocking 1000 ALGO. What’s the difference? Each of them will be rewarded for 7% of their efforts.
I suppose the foundation doesn’t allow voting on something that doesn’t agree with the founding principles, such as voting to distribute all rewards to the richest wallet.
The question might be: are there foundational principles? Like an ALGORAND Constitution?
