Senigata isn't the one crying. Some of the people on a porn pirate site who can't get their jollies fast enough from seeing new lewds of the waifus are.
Comparing different developers with different visions and different operations and different business models is like comparing Nike to Coca Cola. It's in Nike's best interest to churn out new styles every year. Whereas it's in Coca Cola's to "always" make sure their signature flavor continues, "always" - while adding subtle differences along the way.
Again, it's a free game - not just to the 'pirates' here, but to everyone directly from the developer. People can go find a plethora of other things to play and just check in every year or so to see what's going on here, if they want. To expect something more, something different, from this developer after 8 years of knowing this is how this developer works is simply unreasonable.
