I often use Arch in a container, when I need a fhs distro. EndeavourOS is great for desktop use if you don't want to go through the Arch install process.
DeltaChat is an awesome messenger. It's federated, quick and simple to use.
Also, I didn't realize DC was on the fediverse for so many years.
The first part is about the meme. Arch has it's (dis-)advantages depending on the use case.
I wrote the second part because OP mentioned they've found the meme "at deltachat", which is a email-based messenger I use. It's a topic adjacent to linux as it's open source software with linux support.
