AudioBooth is a free and open source iOS app for Audiobookshelf.

HGST was created after Hitachi bought IBM’s hard drive business. It was then later bought by Western Digital.

I no longer use Nextcloud. I use rclone with the smb remote for my NAS.

pCloud has a Linux client. Both GUI and CLI. But I personally use rclone for all cloud services. It is often even more reliable and offers better performance than official clients. It also allows managing multiple cloud services from the same place. It supports client-side encryption as well.

The software is pretty good in my experience. The biggest problem is the hardware was already old when the Pinephone launched 6 years ago. There is only so much optimization that can be done on decade old mobile hardware.

What about it? The Pinephone is still available.

This is also my favorite mobile RSS app. I am currently using it with Miniflux.

I self-host Miniflux. The web client is very good on both desktop and mobile, but I prefer using it with the lire app on iOS.

There is also Collabora Online Development Edition or CODE.

I have had positive experiences with both Radicale and Baikal. I am not sure about the Home Assistant integration, but they both use CalDAV, so I would be surprised if there wasn’t a way of connecting them. iOS has native support for CalDAV, but Android needs the davx5 app (free on F-Droid).

This is where I thought it was going as well.

Proton Mail kind of supports Thunderbird on their paid plans by using the bridge which acts as a local mail server which can then be used in Thunderbird. Tuta does not support Thunderbird at all. Lock-in is the biggest downside of these encrypted email providers.

Thunderbird does not currently offer mail hosting, but they are working on it.

I had to enable the Tethered Network Services anti-feature in F-Droid for CoMaps to show up.

I just run some simple services, such as Audiobookshelf or Wallabag, behind a reverse proxy. After reading the other comments, it does not look like there would be any benefit for my use case.

Yes, I have always used a reverse proxy which seems to eliminate the need for multiple IP addresses. It seems like having multiple IP addresses just creates additional cost and complexity, but I have seen many VPS providers offer multiple IP addresses, so I was curious if there was a use case that I was not aware of.

Yes

Brave is open source.

The 96GB limit is just for Windows. It can be taken higher on Linux.
