Not the OP, but:

Oftentimes data teams have those data sources in the warehouse already (or a process for ETLing new ones in).

Copying data only once means lower costs (maybe) and fewer inconsistencies.

Plus if they’ve done work to join/clean/transform the data in the warehouse they can take advantage of that for product analytics without having to reinvent the wheel in ChartBrew or Mixpanel.
