I've heard of lot of rumblings about various cloud conferences having excessive vendor bias. I suspect I know why.
I offered to speak at two upcoming cloud conferences and have been turned down. Fair enough, I might put a lot of work into speaking but I'm hardly a digerati.
I've then subsequently been told that I could speak if I paid £2,000+ or Canonical hired a booth. Wow, so speaker selection is no longer based upon the topic, the quality of the talk but instead how much cash you've got?
No wonder there are rumblings.
