They are becoming a company, but they haven't committed to become a B Corp. only to "explore" the certification. Like I "explore" using my phone less. ;)

Also becoming a B corp is different from getting the certification. the latter is just a reporting standard.

Bcorp doesn’t mean much. Add some stuff to the bylaws. Doesn’t mean they actually have to follow them. The Honest Company is a BCorp and still had multiple class actions against it and hundreds of FTC complaints.

You can also just stop being one when it becomes inconvenient. That's what Etsy did.
