If you're talking about finding a job now, then I absolutely agree. But if you're talking about what technology developers will persuade their employers to adopt in the future, then developers are the ones who decide.

Employers seem to be influenced by what the developers push (maybe not short term, but longer term it seems to me to be that way). Recruiters go where the employers are. Therefore, IMHO, ultimately its the (vocal) developers who pick the fashion.
