I would speculate there are multiple reasons such as:
1) Pride of Ownership/Denial after spending $30K on a first year bike.
2) Variances in bikes first off the line.
3) Variances in riders perceptions and riding styles. Some people notice things, others don't, just like with anything else.
Wart reports are popping up around the internet for multiple issues (paint, fit & finish, mechanical, software) from early adopters and not just from vendors. Not unexpected for an initial production run.
