epson customer research participation removal

Some months ago on this thread [epson customer research participation removal] it was suggested that users could remove the Epson customer research participation software (Sierra) with this uninstaller: https://epson.com/Support/wa00584

Has anybody done this? I downloaded the uninstaller but it looked like a program that was going to go ahead and uninstall all Epson utilities rather than give me a menu, and I didn't want to launch a process that I didn't fully understand. Does anybody know exactly what this uninstaller does?
