Ask HN: Vendor lock-in is it a thing?

I am honestly wondering just how relevant "vendor lock-in" really is in the majority of the cases. I have personally only worked with one org that was seriously considering porting their cloud infra over to another provider (AWS->GCP, for example). I have however worked with several orgs where concern about lock-in bubbled up, but only as a strawman argument for/against XYZ tech.

So, my question to the community:

"Have you/your org been faced with vendor lock-in, specifically for cloud services such as AWS Lambda?"

A follow up would be:

"If so, how did it impact the project/product?"
