LineageOS is a bad idea as far as security is comcerned since it doesn’t even support relocking the bootloader which is required for secure boot. Strongly recommend GrapheneOS instead. Sadly only works on Pixel phones but what can you do, they’re the only phones whose hardware security features are available for alternative operating systems. Get a used one to avoid supporting Google.

LibreOffice is amazing on Linux, ngl though it is a bit unpolished on both Windows and especially Mac.

It will still be sold at a fraction of what Apple charges for their far inferior SSDs.

Don’t threaten us with a good time.

Don’t know how Fritz compares to other big router companies but I’d personally go for an open source router like the OpenWrt One instead.
