That's just an example guess, but the bloat is there for a purpose... I'm pretty sure the app gets updated on intervals too, just like so many others under the guise of "security or functional updates".
We're in an era where data is weaponized for profit maximization... The most simple and seemingly benign data sets when combined strategically can work against consumers deeply.
We need app audit boards now, maybe even on a government level, and specific detail of everything apps do to be displayed in app stores. There should be serious consequences if apps are found to do things that are not detailed in their release/update descriptions. This collected data can persist forever, and be used in some of the most destructive ways.
Device/OS makers also need to do better at preventing/partitioning non-essential apps from collecting data they don't need access to...
Likely reasons why this isn't already in place is because most don't know how it happens, and many others are invested in these companies, so they turn a blind eye on regulation of them.
