Fortunately this is the last Google product I was still using, so after this migration I will be 100% google free, which will be a great day.
I don't know Squarespace as a company, but looking at the wikipedia entry, they are a publicly-traded American company on the NYSE and appear to have removed websites that promoted bigotry or hate, etc. so how bad could they really be? https://en.wikipedia.org/wiki/Squarespace
This is exactly the problem. I don't go to a domain registrar to be my parent and/or make social decisions for me. I go there to register domains and manage DNS records, that's it. That Squarespace management felt the need to assert themselves into that process with social contagion related matters is deeply concerning and frankly, a deal breaker for me. It'd be like AT&T cancelling your phone service because they didn't like the content of your conversations.
