I'm in engineering of a financial services. When we built our front-end UI for eKYC our marketing requested for google tag manager / facebook pixel and various other tracking features to be built.
I had to fight hard as an engineer to make sure that it does not happen. We had meetings after meetings, and it took a lot of effort for me to explain the risk of data leakage. I was questioned on my "insecurity" for not "trusting" people. It was not a nice experience. I had to inform them that tracking needs to be dealt with properly, not just lazily install google tag manager because it gives marketing 'flexibility'.
