Why is this in privacy? Because it’s an obfuscation, which is good, or because there will be another database to be hacked, which is bad?
I was disappointed they didn’t go for a system like these three words. Or just structuring their addresses around street names and house numbers, like normal people. If you don’t know: currently, addresses are not written as 123 Example Road but mostly as Subdistrict name and number, Block number, House number. The splits into numbered subdistricts is fairly random, the block split just fairly less random, and the house numbers can be in order of building completion so number 6 can be next to number 13. Most streets have no name. It’s so utterly absurd that even if you knew the address there is no guarantee you will actually find the right place without a map provider with correct addresses. It’s a miracle not more people die because first responders couldn’t find the right address. But they don’t change this system, no, they just exchange one incomprehensible system with rando numbers and letters! Well done, the Post Office.
The solution should not be one single provider. Use Ente for pictures, maybe Proton* for other cloud storage and Docs replacement, look into a Nextcloud server hosted by another provider for calendar and email. Don’t put all your digital eggs in one walled nest.
*Proton is plagued by a CEO who can’t keep his mouth shut about politics. Look into that and how you feel about it before you sign up. Their VPN is good but I wouldn’t use them also for email to make switching less of a headache - and I don’t think you could use your own domain there anyway.
