Well, the good thing is that if you are going to piss off anyone, if will be ones with little to no Hive Power so they can't downvote you. That said, the sad reality about hive is that there are basically 2 ways to do reasonably well. Eiher you get withing the 'curation autovote circle'. Many of the curators I would say also mostly just care about the rewards they are able to get with it and have a list of users they curate over and over again of which they know the content at least looks good. This or you are in an 'upvote 4 upvote' autovote circle which has the main difference that you actually need a ton of Hive Power for that. The main problem there is that it often leads to rather low effort posts just to capitalize on the upvotes.

If you fall out of these 2, Hive is a massive struggle and you are lucky if a payout on a high quality post gets to 1$.

Having KE requirements for curation projects should in theory make it a lot easier as it's a factor that everyone has in their own hands.
