> Who can just whitelist phone numbers? I get calls all the time from numbers I wouldn't have known to whitelist; colleagues, people in other companies who I'm collaborating with on some project, food delivery people, customer support calling me back, etc. I assume most "whitelist" approaches don't actually send the messages nowhere, they just remove notifications so they don't interrupt you. For colleagues / etc, you can just use Signal (or whatever company-imposed collaboration tool exists) to hold the conversation completely, or barring that you can at least schedule a phone conversation in advance (so you can whitelist the requisite number). I'm sure if you're client-facing / in sales you don't have this luxury, and you'd rather be interrupted at any time even if it's spam, but I doubt that describes most people. Same is true for food delivery etc... if you're expecting something that might require your attention, you can disable the whitelist and let any call through during that window.
