Well for one thing, I value my time. Dealing with getting a new service provider because the last one just decided to stop doing business is pretty low on the list of things I'd like to do with my time.

For another, Google has a ridiculous reputation for customer service. Even saying that is being generous, because most Google services just don't have customer service, at all.

I keep hearing "just go with someone else if they shut down" - so there clearly are alternative services available, presumably ones for whom providing a fibre service to customers is actually a core part of their business and revenue, rather than a side-gig of questionable long-term value to the corporation.
