I'm not sure I agree with him, one should never close their doors in business.
I personally don't like what GoDaddy has done with the 25% no nameserver commission so I removed my domains from godaddy auctions and dan.com but I don't think I would close my accounts or not do business with them.
GoDaddy has some really good innovation lately and I'm excited to see what they have coming next.
I figured if someone contacts me from godaddy for a domain the buyer now has to pay the commission since my domains are no longer listed. I had them contact me like that on a domain already and I have to say the Zero percent commission is quite attractive.
So for me godaddy has gone from 9% dan to 15% dan to 0% dan.
Truthfully, they probably will get 5% from me because I intend to push my 10k plus sales to dan or escrow depending on how I feel.
So yes we can lessen our footprint at godaddy but I would suggest keeping all doors open to maximize the potential of any future sale.
