This message only clearly shows that no matter what 0.7 is in volume and quality (and it is unlikely to seriously surpass even 0.6, not to mention the amount of previous patches), there will certainly be those who will have enough of it. Judging by the content of this comment, 1\10 is enough for them. They will find 1000 reasons to blame anyone, anywhere, except the developers.
I would understand a similar message from the developers (since they are as sincere as you think) - doing 1\10 of the work and getting the same money as before is the perfect Italian strike. But from ordinary users? No, please, I have not yet become so disillusioned with humanity as to believe in the existence of individuals who protect other people's interests to the detriment of their own. The "money=result" model is something that should be axiomatic throughout the gaming industry without exception. If the development team does not know how much money they need to develop the 0.7 update (it's so difficult to calculate how much you spent on 0.6 or 0.5), then let them turn off donations when the development period becomes comparable to the development time of the previous update. Or it will pay fixed amounts of payment for the upgrade.
Collecting donations when the only guideline for donating is a constantly changing sign that has nothing to do with reality (I remind you - the current sign on the site clearly says that the update is ready) is a scam.
