I've never publicly scolded someone for doing free work for tech monopolies but I do understand the impulse. The problem is that it's a completely one-sided relationship, and there are perfectly legitimate concerns about how the biggest tech companies are using their wealth and power. At this point I doubt much of anyone would expect a large tech company to go out of its way to lose money in order to support human communities. They take what they can, and ruthlessly kill products and services the minute they think it helps their bottom line.

Google and others don't need to rely on free volunteers, but it's certainly more profitable for them. Does Google making an extra $10B/year make the world a better place? Maybe, I don't know, but it's not crazy to think the answer is no.
