What is ample time for a company that hired a webdev one time to build them a static website and never checks webmaster@domain emails?
That kind of outfit is much more likely to be a victim of missed renewal or a myriad other technical screwups than a Google-initiated exit of the registrar business.
I feel like Google marketing has no idea the absolute monster of a problem they've created by allowing their business to get a reputation for being extremely unreliable in the B2B space.
They can certainly count on a spate of hyperventilating HN posts whenever they announce any kind of service-related news.
More seriously, their most celebrated servicides are consumer-oriented, like Google Reader. "Extremely unreliable in the B2B space" sounds like an exaggeration to me.
I'd also suggest just bringing your tone down, this isn't a fight and calling people on the other side of the argument "hyperventilating" doesn't really do anything to promote meaningful discussion.
What is a reasonable money expenditure to migrate off a platform when you could look at the company record and see that you're much better off just choosing a different platform? Is a week or a month of dev hours worth putting your faith in a company notorious for randomly shuttering products?
