Here's the thing: I don't use Patreon. I refuse too. I have found in the past that Patreon is biased against certain political leanings.
I personally believe that platforms such as Patreon, Itch and Subscribestar should not have any such biases. They should be completely neutral, only concerning themselves with good customer service and following the law.
So I refuse to even click on Patreon much less support them financially, even if that financial support is indirect.
Which means if the Dev doesn't share news here on Itch I will never see it. Which doesn't exactly help me to feel like I'm part of their community now does it? And it doesn't take a lot of effort to copy and paste a post from one page to another does it? Maybe just a little editing to remove any references to services only available on Patreon...
So when a Dev fails to share news across various platforms it just seems lazy to me...
Last thing I'll say for now is that the love of art should be a powerful motivator too shouldn't it?
Lets face it, writing is hardly the most profitable occupation. If it was there would be far more George R R Martins or J K Rowlings in the world. But that sort of success in writing is exceedingly rare.
As for the notion that the Dev may have IRL issues that are slowing them down... well either he is an artist and can take his time for the sake of his art or he is a businessman providing a product he wants to sell, which means keeping his customers happy (Which means getting his product on the market before he loses their interest).
He can't be both, those two priorities really don't match. You can try to do both but one will always win over the other in the end.
