TAILS, the distro for tor/darknet usage, says that people should not use Etcher because the program sends telemetry data back to their servers, ie it records your IP address and what type of distro installer you made.
TAILS is currently recommending that people use Rufus instead. There is also another program for creating bootable USBs called Ventoy.
I always make bootable usb using the simple 'dd' command line tool.
