For sure that can be the case. But what does this mean then for the entire suite of Google services? Their entire strategy up until these new paid-for services predicated on giving people free services (Gmail, Docs, search) under the assumption they could pay for the development and support with ads. It seems like they're shifting to a model seen by open source software creators - free to use, but any extra features or support will cost extra.
