| Complete nonsense, as anyone who has worked on a service with scale would know. WhatsApp is not even close to the same architecture as it was at the time of acquisition. Not to mention the load constraints did not grow 7x, it's orders of magnitude more load increase than that. As the world's mobile data speeds have skyrocketed in speeds and plummeted in price, WhatsApp is now handling orders of magnitude more data per user than when they served merely 450. And it's all complicated rich media which was not handled at the time. WhatsApp's file limit at the time of acquisition was 16 MB. Today, it's 2 GB. Per file. It didn't have voice or video calling at acquisition either, also highly complex and expensive to run. WhatsApp grew 7x in user base, but the scale of data and technical complexity grew exponentially more. If this were so easy, history would not be littered with high profile scaling failures from messaging apps. Most notably Signal, which couldn't handle a 1.5x influx of users from WhatsApp and was down for weeks. Claiming a 7x scale is technically easy while your data-per-user growth grows probably 50% a year or more is patently ridiculous. |
