Again I get where you're coming from ... but ultimately they owe you nothing ... you haven't payrolled this VN, or contributed Art, Music, Dialogue, Edits, you haven't done anything besides take part in experiencing it.
I'm sure the DevTeam is glad you're passionate about the VN, that's awesome! But just because you are enjoying the VN doesn't mean you are owed anything...
If they don't want to send out an update right now, so be it. You just need to accept that and wait patiently like everyone else, and doing anything besides that could risk antagonizing the Devs to the point that they may not way to continue updating the VN...
Again I do understand where you are coming from, but ultimately you just need to be patient, quiet, and support the Devs in any way you can. :)
