That may be true for some definition of informed but I'm inclined to think that there are many informed people using gmail (and other Google services) and this fact leads away from your assumption.

But it's perfectly reasonable to think that Google might drop a service like "Sites" if they aren't able to monetize it, or if they think that it competes with another of their services. It isn't currently reasonable to think that of gmail.

Nor to think that of [voluntary contribution supported] neocities?

But my neocities website was arbitrarily shut down just a couple of hours ago. And I must wonder if it was the only one.
