It is not one person taking from the reward pool. It is a group of people giving to that person a reward.
Nope, it's the first: that's how the reward pool works. The second is more of a tipping system or a patreon style system, but that's not steem. There's a limited reward pool supply, so if you take from it (and you are taking from it if you didn't choose to decline rewards), then you have reduced the reward from everyone else who is also electing to take from the reward pool.
Reading your post I got the feel that if it is published or posted anywhere, ie:Internet, newspaper, video, magazine, or newspaper or anywhere else that stuff gets "Published", it would not be allowed to receive a vote for a Reward on Steemit.
That's not what I'm saying. I'm more concerned with the value given under the assumption that it is written for Steemit. If you read my post I address this when I talk about crossposting. It's fine as long as the voter or purchaser is making an informed decision.
Authors, Content Creators, or posters, are not telling anyone they need to vote for them. Most of the people under a 65 Rep, have no footer asking for votes, resteems, or comments. So you are saying that by the simple act of not declining a payout they are taking from the Reward pool? No people are rewarding them for their content, they are not taking anything that was not freely given to them.
You can not ask people to come to steemit where they "might" be rewarded, then treat them like a thief in the night when people decide that yes I want to reward that content!
I am guessing that is pretty much aimed at published Authors that are "Serialising" their published works for steemit. Those authors all (at least the ones I have run across) have links to their books on Amazon, or where they are published elsewhere. What they are saying is, You can read it here for free exclusively on steemit, you will not find it on facebook, google whatever, or reddit style places, here and available for purchase on Amazon. Stating it is serialised for steemit is not "Crossposting".
But yes I know there are a lot of sour grapes out there, the new users of steemit are frustrated with the actions of some early steemit adopters, (2016), and how there is a seeming double standard. I am amazed every time I see someone with a rep over 60, downvoting a new user because they asked for a follow, when the 60REP person has a footer stating upvote,follow,resteem. There are much larger issues than "regulating" when a post is considered to have been cross posted. We need cheetah bot and steamcleaners for plagiarism and flag abuse. not to regulate what can and can not be posted because it is posted on another site the Author owns.
"not to regulate what can and can not be posted because it is posted on another site the Author owns"
As far as steemcleaners scope is atm, we have no problem with someone posting their work that they published in other places, as long as they confirm the authorship to prevent idendity theft or plagiarism.
If they recycle their own older content, they can still be auto caught by cheetah though.
"Most of the people under a 65 Rep, have no footer asking for votes, resteems, or comments."
From my experience working for steemcleaners, it is rather the other way around.
New users and low rep users then to have those glitter, cookie cutter footers asking for resteems and follows, with loads of whale username tags spammed and shiny icons that often take up to 80% of their post content. They also spam posts with their trash comments with "nice", "interesting post", "please upvote me", etc.
Often, regualry fishing on bloggers who always reward every comment. There are whole farms by scammers that open tens of accounts (with little or not blog activity except some resteems) to just comment fish on these generous users.
When you go to trending page and check up posts there, you will notice that only handful may have such footers like "please resteem, follow, upvote".
Also, there is a difference between asking such things on your own post, in your blog, and going out there to spam comments with such crap as low rep and new users tend to do.
