It’s not that easy to leave Google or Apple. As an example I wanted to leave iCloud and stop paying storage tax for Apple. But they have made it almost impossible to migrate the photos. There is no API to download the photos programmatically and the only way is to sync all the photos to MacBook and then move it. However, the photos are close to 1TB of storage and my MacBook doesn’t have enough storage to sync all those photos locally.
Same goes for Gmail. I have used my Gmail address for countless services and it’s almost part of my official identity. The benefits of moving away from Gmail doesn’t justify the effort I have to put in
