? Did you read what the article? The change here is pretty minor and just reserving the @name.bsk.social if they verify with a domain to something like @domain.tld
Now, users that verify their account by linking their domain name get to automatically keep the default @username.bsky.social username
That’s not what they are doing right now
I’m also going be real that this is also the least of my concerns for a platform. If they make some people change their handle that don’t need to, it really isn’t a massive deal in the grand scheme of things. Especially since when handles are changed on Bluesky, all the references to that handle also change because they have a constant ID for all accounts. Impersonations leading people to scams is a much larger issue
