The Merriam-Webster definition of innovation is:
1 : the introduction of something new
2 : a new idea, method, or device : NOVELTY
So, instead of promoting something new, you could be said to be promoting something the same as everything else.
In other words:
"I'm an agent of imitation."
2 : something produced as a copy : COUNTERFEIT
: resembling something else that is usually genuine and of better quality : not real
Alternatively, rather than talking about introducing something that isn't new, you could be talking about doing something that takes away from what already exists:
"I'm an agent of deterioration."
: the action or process of becoming impaired or inferior in quality, functioning, or condition : the state of having deteriorated
// rust deterioration
// the deterioration of academic standards
1 : to make inferior in quality or value : IMPAIR
// Exposure to sunlight may deteriorate the paint.
