If you're suggesting Cathode might be ripping off Cool Retro Term, I think Cathode[1] (Jan 25, 2011) predates Cool Retro Term[2] (Nov 22, 2013) by almost three years.
Cathode was also more full-featured, e.g. I don’t think CRT has sound effects or the dying tube effect. It’s been a while and I’m not on my computer but I’m not sure it even has the bitrate modifier.
