Well, you wouldn’t expect it to in the growth phase.
A lot of consumer-facing Internet companies have a large portion of their costs be fixed costs. That is, a programmer or QA guy costs the same amount whether you have ten users or ten million users. But your revenue is linear in your userbase size. So you really don’t want to be a small company, if you fit that profile.
The idea is to burn money and grow rapidly to the point where your fixed costs are relatively small. It makes no sense to try to generate profit if you lose growth for it.
That’s especially true for social media companies, because for them, network effect is a major factor – the value of the network is something like the square of the number of users.
So you really want to be big, not small.
So the solution is to grow quickly, lose money during that period, then adjust and monetize the userbase when you can’t afford to burn money growing any more.
That transition to a profitable state after a money-losing growth state usually means that a company is gonna do something unpopular (since they’re optimizing for something other than appeal) and what Corey Doctorow was complaining about as “enshittification”.
The fact that Reddit lost money during the growth phase doesn’t mean that it was a failure – that would have been intended, part of the business model.
Now, if it’s losing money once the growth phase is done, that could be another story.
