I think this is a bit of a storm in a teacup myself and just creating drama where it need not exist. If someone is attacking your business, go to them, call them out on it and take action accordingly. Don't create this drama of "mysterious somebodies in the WordPress community doing under-handed things". It serves no purpose but to shock and scare. While I'm sorry to hear of what happened to WP Site Care, this does little for the community, except to fragment it.
