*waves hand* You don't require additional permissions to my google account.

Big companies who do business online want as much customer data as possible. Sometimes it's just a blanket "give us all permissions so we don't have to keep sending you reminders and you don't have to see them" and a lot of people will just click through to make the pop up go away. I agree with OP. SWGOH can see my in-game activity and payment info for purchases, y'all don't need anything else. Why do you want to touch the Google Drive?

I think it's mainly for feedback/technical data and consumer tendency information across the board for the game as a whole to better suit the communities wants and needs for updates to make the game better. No big deal imo.

Right up until EA decides that you're playing games that are similar to their offerings and shoves ads so far down your throat about those games that you eject cash on the other end, if they want player feedback (or others), it's often better to ask than steal.

From a purely technical perspective, this wouldn't benefit the game, but rather sales and 'insight', which is often data harvested from you and then sold to other companies. Always be mindful of the profit motive, Padawan.

In the end, though, if you're ok with everything about what you are or aren't doing being visible just so you can play a game, I suppose that's your right.

Id agree with that, if they actually had a support team with actual tools to do anything that isnt just copy and pasting the same script.... 

Get an actual support team, with actual tools, and id be willing to share my technical data and consumer tendency information. 

Yes this is BS, they should not want access to your Google Drive.  This is a breach just waiting to happen.  Anything that comes through from them to your drive comes down to you.  If they have any XXS vulnerabilities and it gets exploited oops sorry won’t cut it.
