Why do people dislike Chris Martin?

As the title already states:

I frequently encounter posts about people either disliking Chris Martin or his voice.

There has already been a post about how many dislike Coldplay for different reasons, but I'm actually interested in knowing if there's a specific reason why Chris Martin is often mentioned in that context (except of him being the "face" of Coldplay).

As a Coldplay fan I'm of course incredibly biased, but I'd like to get to know other opinions.
