> tenth marketing platform integration the engineering team will hate the marketing team

one-time problem during setup of someone's infrastructure

As the marketer regularly making these requests, it's by no means a one-time problem, and I can attest to being hated by our tech team (for some reason they don't appreciate me hiding random JS code in our CMS to save on these requests either...).

GTM would solve many of the problems for us as we store all of our customer data in CRM anyway, but for other orgs that don't have a massive CRM policy, having an essentially outsourced data warehouse might be valuable.
