if you choose to support that's on you, choosing to support when its OPTIONAL doesn't give anyone the right to demand updates, if it was a paid-only game then it's understandable
don't you think the dev is leaving it free for now because he knows he won't be able to make consistent updates?
That's up to him, he could have charged a price from day one. But maybe he knew he preferred all that income from Patreon, so said, "i'll leave it as a free option on Itch, so no one can complain about how I care more about my Patreon customers, and barely care about my itch customers.
I want to know why you are such a big fan? Are you one of his Patreon customers, paying $5 a month for 10 months, so $50 with no update, but you don't care? To be honest, I find your attitude strange?!
