And I'll stop you here. It's less than obvious that there's no obligation. If you provide a critical service that folks rely on at a price less than your cost, you drive out competition, and it's a critical part of your own business model, dropping the service without warning is IMO on the border of what Google should be allowed to do.
Corporations aren’t magical entities that somehow exist outside of social obligations and can do whatever they want as long as their own terms of service permit it.
Maybe $1/month starting in 2 years, then increasing to $2/month for the next year, $3/month for the next, on until they feel they're covering costs.
That way it gives people time to look for alternative free providers, or time to get used to the idea of paying for email.
Where's your support for this statement in the law?
In the broader context GP is clearly advocating for what the law should be, or should be changed to should certain events come to pass. Demanding support in existing law for a proposed change in law is nonsense if that's what you meant to do instead of narrowly discussing the nearly vaccuously true quote you pulled out.
I don’t have much empathy for Google.
