The PPS doesn't share the fees? Anyway, I don't see how a direct donation to the pool helps more than just making it a tx fee.
I guess my understanding of how a pool gets the fees with the block it finds is different than yours.
Pools collect a percentage fee from miners, not all the fees from the block.
EX: Pool collects a 1% mining fee, so for every 100 coins a miner receives the pool gets 1 coin
So when a pool says that they get the block fees, what are they referring to?
(From BTC Guild)
.....at a 3% fee, which has some variance, but also includes block transaction fees.
What that's saying isn't that it's getting the TX fees in the block, but rather 3% of the total (block+fees).
Say the block is 20 coins and has 5 coin in fees on it, the pool get's 3% of 25, not 3% of 20 and then the other 5.
This depends on the pool of course, but a poll that claims all the block fees aren't going to get many miners. That's like a diner manager that takes all the tips, that's just a douche move.
