This is the point here.

Many people have no idea of the infrastructure and costs needed to run many of these servers that provide services to people.

I disagree with things like Adobe basically using it for DRM but have no issue for services that are literally serving millions of people and providing something worthwhile that the majority of the population would otherwise not know how to do on their own.

There is some nuance to it, like offering a service and then slowly creeping costs up or adding an advertisement tier and dropping everyone to that etc is crap. But in general, if they are providing a decent service then I don't really have a problem with it.
