If you dislike change, you're going to dislike irrelevance even more
Like it or not, traditional IT is under existential threat. Some won't manage the change to a service provider model and then wonder why their functions get outsourced.
Yes there are realms of stories of end users screwing things up and IT having to clean up. I've dealt with more than a few over the years. That isn't a guarantee of job security nor a good reason for IT existing.
IT serves the business as much as any other function, end users will always make poor choices, but ultimately they are the business, they understand their needs to work effectively and IT should facilitate those needs, not dictate a model that suits it.
Getting data in to your company is the growing problem.
End users increasingly have a choice of alternative service providers and shadow IT is growing. Perhaps things will swing back in house over time, but right now things are going the other way.
