I'm all for piracy. Hence why I upload my own VN here for free a week after anyone who financially supports the project has gotten it. Fuck Adobe and their subscription services. Same goes for anything of that sort. But I do have a problem with people who consciously steal shit, make a profit from something they didn't make, and then advertise it as their own intellectual property. Hiding and/or putting attribution to the original games in small print just as grimy. He could've just as easily put it in the overview/summary.
I'm not taking any ground, just calling it what it is. Once again - Piracy and theft/plagiarism are two different things, and legally, are treated as such. The reality is that an overwhelming majority of developers willingly upload their VN/game/projects here as the sheer size of F95's userbase allows them to get a ton of eyes on them. In that sense, F95 has become and is basically a more of a free, non-F2P, dev-friendly (in most cases, at least) Nutaku. Reddit is dead, Twitter is slow-growing, DeviantArt stopped being relevant years ago. Whereas F95 has 10,000+ users online at any given time. It's quid pro quo; make a good game/VN and the financial support will come more often than not. Most likely from this forum.
Plagiarism - using someone else's ideas or words without crediting the source and pretending they're your own. No, crediting the developer's renders isn't proper attribution. Especially when you're (attempting) to make a profit like said dev. Is he using other dev's renders without permission? Yes. Is he incorrectly attributing the games and their devs/authors? Yes. Hell, he probably UnRen'd someone's VN and copy-pasted his code.
Piracy - the unauthorized use, reproduction, or sharing of copyrighted or patented material – typically music, movies, TV shows, and software. Are we pirating his music/movies? No. Are we pirating his renders/animations/etc? No. Are we pirating his software? No. Are we sharing his copyrighted material? No.
