The German tank production capacity was estimated by serial numbers of captured tanks. There are ways to read all kinds of information by observing energy usage. High resolution time and sequence data undoubtedly reveal more than you’d like.

Most of our lives as boring SaaS etc. software developer will not be near as exciting as this, but of course you may never know.

I parsed the EV chargers APIs where I live (using Frida in Android) and one of the fields returned the daily revenue and profit.

Could be quite useful information to competing charger networks or in future M&A discussions.

I've seen a project for a trading firm that inferred all kinds of traffic and revenue numbers for companies before their quarterly earnings were made public. It wasn't perfect, but knowing with a certain confidence level whether the numbers were going to be better or worse than estimate was profitable for them.

Sure, for many places it doesn't really matter, but if your URLs or user ids can be seen/scraped by others, you might expose some commercially interesting information to competitors.

And the indexing argument isn't really compelling, is it? You lose very little by sticking to fully random UUIDs.

Here in Ukraine trying to estimate enemy's drone and missile production capacities by serial numbers of their parts is quite a mundane task these days.
