Let's try to come up with an analogy. In this case, GoDaddy is eBay -
25% For using an external lander -
This would be like listing a product for sale on eBay and Facebook marketplace.
If the product sells on eBay, instead of charging a normal fee, eBay tacks on an extra 10%.
Then eBay tries to frame their normal fee, as a "reward".
Afternic pricing policy on your landers -
This would be like eBay saying if you have a product listed there, you can not list it anywhere else at a lower price. You want to ask a lower price on Facebook marketplace, because there is no fee? Tough.
These policies sure look anti-competitive in that context.
