I think maybe folks got the model number confused. There are strips where the entire signal is passed verbatim without being reformed to every package on the line, but everyone stopped using them because they're awful. In my experience, slow microprocessors are WAY more tricky to deal with than a 3V3 logic voltage for these strips; and often lead to crazy hacks. I'd way rather just put a modestly powerful resistor or a buck converter in my project than deal with trashy old Atmel chips, given how absurdly cheap ESP32 and ARM M7 packages are.
