There is a lot of FUD whenever someone mentioned third party because many don't know the difference between a dedicated analytics provider and Facebook.
How would you know a difference, how could you trust the difference (given the adtech industry being what it is), and how can you know things won't change over time? All that without being in a contractual relationship with that third party.
Are you in a contractual relationship with AWS for every service you use that uses AWS on the backend? How about Loggly? How about BigQuery/Snowflake? Intercom if they use that? Salesforce? Facebook and Google if they run ads? They may not do anything weird with your data now but how can you know that things won’t change over time?
