I'd take from the curators if from anyone, the content producers long term are going to be what matters. We can see this issue already with Youtube, all the content producers are complaining about the company taking too large of a share and content producers not being profitable enough. Long term, I don't think the average user will value their curation reward all that much, because most content consumers will not have much SP anyway.
But 10% is way too high, the 1% makes more sense. 10% is huge and a danger to decentralization long term, while 1% is not something I would worry about.
