I see this too. I can’t speak for all developers, but the ones I watch do this. I am interested in 3 developers, 2 of them I support: DPC, NLT, Ocean and each of them does this. For example, DPC decided to make a video at 60 fps. With this, he simply decided to stretch out the time and do nothing and receive money from his patreons for this. NLT completed its game last year, and now it is stalling for time, releasing riddles and all sorts of pictures once a month that are of little interest to anyone.
Ocean constantly needs money for new video cards, but at the same time his rendering speed does not increase, but rather decreases. For example, Ocean made Chapter 5 using 2x3090 and 2xA6000, and at the same time, his work speed was less than when he made Chapter 3.5 using only 2x3090. In addition, he releases empty chapters in which there is no more than 10% of the plot, and the remaining 90% are conversations that make no sense. DPC also has conversations that make no sense, but there are fewer of them and they are not as noticeable, because he makes chapters 3 times longer than SG.
