Clearly Squarespace is the guilty party here, but man, I am still upset Google shut down Domains, and can't help but direct some ire their abandonment of yet another product.
I remember reading the Domains announcement and thought to myself - “you have to be a fool to trust Google to host your domains long-term”. Feels good to be right, but I feel bad for everyone who jumped on the bandwagon. I cant imagine trusting Google products to last those days.
