According to The Daily Hodl, Balaji Srinivasan, former CTO of Coinbase, stated in an interview on the "Impact Theory" podcast that "if G7 countries decide to allow the confiscation of digital assets, then tech giants such as Apple, Microsoft, and Google can lend a hand. Countries may decide to confiscate digital assets in the future in an attempt to recover from economic turmoil. Tech giants can easily scan our devices, find private keys, and hand them over to the authorities if they are ordered to do so."
Srinivasan further stated,
The biggest risk factor for that is actually Apple, Google and Microsoft because they have operating system access. That’s actually what I’m most concerned about: it is the fact that Apple has software updates and Google can get into your Google Drive and Microsoft has Windows, and if ordered by the state, in theory, they could scan your hard drive for private keys and then pull your digital assets.”
