Was looking for this comment and was also not surprised by the reply that Google will disable it.

Google sites is a great service, that started about 20 years ago. It won't get killed.

Except they'd probably graveyard it in a year or two...

IMHO Google is the LAST company you'd want to trust with a simple small-business site. They will often release something and never update it again, and offer zero support for any issues you might run into.

If you can't even pay them for it, they have zero incentive to improve it.
