Most people only relate Linux to Ubuntu, Linux init system to SysVInit or SystemD, Containerisation to Docker or Kubernetes, Linux desktop to Gnome.
In some cases, it may be due to official support being available but most of the time it's just that people are being taught Ubuntu first as "THE Linux" and that's what they use since then.
nowadays I assume cracked software (unless if the crack script is fully open source) to likely contain some kind of malware and I just sandbox them since I play cracked games with bottles flatpak anyway.
