I remember the "made without computers, samplers[...]" note on their first record. Using technophobia and reactionary lies (the record was actually produce with excessive use of digital effects, the artwork mostly plagiarized and digitally layouted etc)

The liner notes read "no samples, keyboards, or synthesizers used in the making of this record". They used pedals and live feedback for distortion and effects, but did not use samples, keyboards, or synthesizers. At the time, as you'll know, synths were either embraced as an evolution of music production or derided as an erosion of real musical skill; RATM were in the former camp and their claim – as far as I know – was genuine. It doesn't matter where you stand or stood on the debate, it wasn't misleading or false. Your outrage is manufactured.
