I count about ten people who agree with you, out of seventy posts. I guess you can count that as "many".

C&D: It's Time For Toyota To Kill Scion
Scion is a brand conceived in a focus group, born in a fluorescent-lit marketing department, and wet-nursed by copious spreadsheets and PowerPoint presentations. It can claim no pedigree, no history.
