I don't know any of the top witnesses to know the motivations and can only base my conclusions on the affect the proposed 50/50 idea would have on my account and those I follow who have not been as fortunate as myself in finding support. It seems obvious to me that this would increase the take of those at the upper scale at the expense of those at the lower end. Perhaps it is not so obvious to those at the upper end, however I find it more credible that they do know it would increase their share of the pool and at whose expense it would be at. I saw another user (@glenalbrethsen) make a comment that summed up my feelings on this proposed reward cut they would have me receive.
At the same time, I want people to have a chance to make it on the lower end, too. I don't want to be a gerbil in the wheel of someone's passive income stream, though. If they're so concerned about curation and the long term health of the platform, why aren't they curating now, rather than delegating or running bidbots?
As for the flagging, I will admit I have never been much of a flagger, only doing it to one person who has a grudge against canadiancoconut and familyprotection who couldn't stop trolling month after month. I will admit I am in a bubble here, having found my favorites for my feed and finding new people of interest from their comment sections. Which is how I found you as well. When I log in, it is more of a mind to read posts that interest me, curate them and when I am ready to post after researching to do that as well. And to support causes that I align with. I don't see myself changing this approach regardless of any proposed changes to the flagging system. I have enough people in my life who I oppose to desire seeking them out here. For me, there are enough blessings here to spend my time on. You being one of them. I appreciate your knowledge, even though at times it falls far into my ignorance zone. You are one I wish would post more on subjects as you have much you could share that deserve light stronger than in comment sections. You are one of the brightest I have encountered here on the platform.
