This article misses the most important reason to not use Serverless: Cost. It's way more expensive to run serverless than it is to run any other format, even something like AWS Fargate is better than Lambda if you keep your Lambda running for 5% of the time. The second one is even more important though: Time. How many of my systems are guaranteed to stop after 15 minutes or less? Web Servers wouldn't like that, anything stateful doesn't like that. Even compute-heavy tasks where you might like elastic scaling fall down if they take longer than 15 minutes sometimes, and then you've paid for those 15 minutes at a steep premium and have to restart the task. Serverless only makes sense if I can do it for minor markup compared to owning a server and if I can set time limits that make sense. Neither of these are true in the current landscape.
