I am a bit behind in catching up - thanks for sharing all that, both the topics with the PyLova devs and making sure I was kept in the loop as well:-).
I don't recall the prior issue, unless it was the one with user blocking being silent. On that one I was swayed by the argument that it simply had to be that way due to limitations within Lemmy. Which made a lot of sense to me, since that happens a great deal actually. e.g. PieFed offers polls and user and post flairs, all of which Lemmy will ignore, as is its right and choice to do so.
But the vote quota crosses a line where iirc it doesn't even tell other PieFed instances - nor Mbin nor nodeBB nor Mastodon etc. - what is going on. It's horribly designed, or at least it was upon release and if it has changed since then I have not heard of such. Some features take literally years to be implemented, but this one is slammed down everyone's throats against all objections to the contrary without anyone seeming to have been heard? Sure, whatever, Rimu can do as he pleases, but it makes it really hard to hold out any hope for the future of this project when people keep losing investment in it (now Snoopy having become the latest casualty, seemingly? at least it appears that way).
The Innuendo Studios YouTube series The Alt-Right Playbook does a superb job at explaining how someone can fall into authoritarian thinking. It doesn't so much involve logic as emotional manipulation. Particularly interesting are those in the outer circle of the onion-like layers that are shocked, Shocked I tell you, SHOCKED 😲 😳, when they find out that the people who had been screeching all along at the top of their lungs who they are, suddenly start doing the very things that they always said that they were going to do if they only had the power to make it happen. With perhaps just one or two... "minor" adjustments, which now place them on the outside rather than in, as the enemy rather than beneficiary of all the absolute violence and horror. Like the target rather than the perpetrator of a genocide.
It really helps to realize that sometimes people lie on the internet.
PieFed is growing, agreed, though mainly due to lemmynsfw.com having fallen and chosen PieFed as its replacement. Which is valid but an outlier, skewing the stats heavily by just that singular data point. PieFed is still growing despite that though, just not by nearly so much or robustly, if all the decisions about planned migrations that were cancelled as a result of the daily vote quota issue do not get reversed or replaced by others.
I've brought up the topic of separating downvotes from upvotes with Rimu years ago, it seems very unlikely to happen. Mainly because he does not want it himself, therefore does not want to expend much effort to put it into the code (understandable), and also it is legitimately a difficult UI issue that he prefers to leave to others. PyLova has already done it though, as you noted, along with so many other things that Rimu was never going to get around to. Gold lining, even Platinum!?:-)
