Sounds like those are migrating as well.
For customers who purchased a domain in the Google Workspace sign up flow
Once regulatory approvals are obtained and the transaction closes, you will become a customer of Squarespace. After close, there will be a transition period during which customer information associated with your domain will be migrated over time, subject to limited exceptions, after which your domain management will be managed in a Squarespace account. This includes DNS and WHOIS settings and domain name renewal. We will work with Squarespace to make the transition as seamless as possible for you. Billing for your domain will continue to be managed by Google Workspace directly, even after your domain is transitioned to Squarespace.
Memory is short on the internet. Reddit are hoping for this to blow over “quickly” (i.e. in a month or two) because they know the bulk of their users will continue to show up (out of inertia or a lack of viable alternatives). If they can keep the front page showing decent posts, they think they’ll make it through.
I think the knock-on effects of losing mods and “power users” will take some time to play out. The real long term effects won’t be known until it becomes clear that the loss of those key users has effected the quality of the posts and therefor usage by your “average Redditor.”
