I'm pretty confident that those changes would massively impact anyone active on the platform. It will make your $0.01 votes more valuable, since competing with bots will be easier (reading content will actually make a difference).

The real change though is for small content creators. Changing the current reward payout structure directly addresses visibility issues, which makes most posts more likely to be seen & paid according to the value they bring to the site.

Whales also win, since the platform is likely to be more welcoming to new users and the value of STEEM is directly related to user adoption. User adoption has a much bigger impact on the value of their holdings than their curation rewards (even for bot whales, making 1%+ SP/week only in curation rewards).
