Probably stress. Running a business + a nonprofit + YouTube is already a lot. And on top of that I think he's recently been diagnosed with being in the spectrum, which is stressful on it's own way as well. I don't think he'll stop though. Dude's been burning himself like that for over a decade, it's probably the only way he knows how to live.
Off topic, but good taste with bookworm! Praise be to the gods!
If you wanna selfhost your own solution, I can recommend Audiobookshelf. It scraps metadata from Apple, Amazon, Google etc, tracks on a per-user basis at what point in the book you are, can be used in a browser and has an android app. It's easy to set up with Docker too. You can even add PDFs and epubs to the books.
Been using it for a few months and it has been great.
As for sourcing of audiobooks, aside from torrents there are also audiobb.com & audiobooksbee.com . They use RapidGator as host for a ddl.
I found a whole bunch in a place I never thought to look: e-hentai.org Just look for the tag "artbook" and you already find a bunch. Or look for something more specific. Yes, you will have porn in between. Yes, its just the images without text embedded etc. But it's a decent source.
Basically, the repo for the extensions has been nuked by DMCAs. You can switch to a repo hosted by a third party to bypass it. I'm not gonna link one here because I have not looked deep into who's a good host. But you should be able to find one with some searching.
Tachiyomi also released a statement here.
Legacy was the only one I personally got to enjoy, but I very much enjoyed watching Borg as well as Elite Force 1&2.
It was humans under the command of aliens.

Honestly, props to them for disclosing this so early. Other companies have waited months to tell their customers about these things, sometimes only because it leaked.
I mostly agree, however setting your phone number includes the verification process. With that, Google knows for near certain that this is indeed your number.
