I'm against giving part of the block reward to any foundation, this is like premine. No matter how transparent it would be it would still look unfair to many people. The better way is donating.
As you should be.
Foundation = centralization
Centralization:
The concentration of administrative power in a central government, authority, etc.You've decentralized the mining aspect of the coin by negating the mining pools. No need to change that mindset with other aspects of the coin.
