Textfugu is an unfinished product, and the latter seasons in particular show plenty of evidence of that. As I progressed further I found myself referencing Tae Kim and Imabi more and more for extra support, and I stopped studying Textfugu’s Kanji a long time ago. I would’ve dropped Textfugu completely if I hadn’t invested so much money in it (and gotten sidetracked from studying Japanese due to other life events). I am going to shift to another textbook soon, perhaps Genki or the last of the Japanese from Zero books (which I actually liked better for self-study than Genki, though I’ll have to switch to Genki II afterwards). The state of Japanese learning resources in general is certainly better than it used to be, but compared to other languages, it isn’t great overall. I wish there was an unequivocally better overall resource for self-study learners out there, but there unfortunately isn’t much of quality to choose from. Lots of lower-quality stuff put together by non-experts and people who have no formal background in Japanese language teaching or materials development mostly.

It doesn’t feel right to me that Koichi is still accepting signups (and thus, payments) for this unfinished product, but I guess it’s all business in the end. I suspect that the Wanikani money (plus whatever Tofogu brings in) is keeping his business afloat so they’ve lost motivation for things like EtoEto. Ignoring all of the errors and unfinished bits of Textfugu, the fact that much of his practice exercises rely on Lang-8, which has stopped accepting new signups and appears to be in the process of being phased out, is quite telling.
