by installing arch you chose systemd.

The Linux Gatekeeping is a big reason why after 30 years, we've only now got to 3% market share.

if it was as simple as “changing from the default”, most people wouldn’t give a shit.

the problem is that it has parasitically embedded itself as an ever-growing monolith somewhere in the murky waters between kernel- and userspace.

coupled with a bunch of bad design choices, and it taking on more and more system roles makes it so that it constitutes an actual danger to libre software.
