That's going away, because of rampant abuse of Google's services and their inability to shut down pirate movie sites that use redirectors and fetchers to steal links from Google's CDN.
Do you have any sources for this? Or is this just speculation?
Source?
Well given they're shutting down GSuite accounts which upload movies and their continued insistence on increasing difficulty for get_video_info methods to fetch video source, I give it 1-2 months before they stop offering unlimited storage with GSuite.
The accounts recently deleted were sold on ebay against TOS.
