No, no. It's meant for you to share with anyone who might be interested. I only put it in a backer update as something of an experiment, to see if the beta file spread might be different if backers were the one doing the sharing of it instead of me, directly. Feel free to post up the link anywhere that people want to hear more about it. You'll want to link to the folder rather than the individual files, though, to make sure they get the freshest beta and can see the teaser files, too.
