They have obligations to the community, for sure. And those obligations are staying truth to the Patreon benefits they promised, and being as transparent as possible about their work so that people can make an informed decision on whether support them or not. And I'd say they are doing a good job on that regard: every patron is getting their respective Patreon benefits for their money (Discord access, weekly reports, spoilery art and WIPs, voting rights, and they'll eventually get the update 24h earlier than its public release), and if devs decide to 'postpone' the progress as you say, adding 10 more tasks to the counter, we'll know it the very next day thanks to the progress tracker, the same way we got critical info about the reasons for this slower progress. By the way, they haven't said 'we'll update this one day'. That would be leading on people if they couldn't meet that deadline. Their more accurate public deadline has been 'we're still a few months away' when the polishing phase began. So at least use these devs actual behavior when raising your concerns.
Now please tell us what other obligations you think they have or should have.
