I agree, I was a big namecheap user but now it is a dark pattern trap to trick people into addons. Just changing your DNS is a confusing jumble.
Of course they present options during the checkout process, which is slightly forward, but reasonable as a business.
However, (1) the defaults for all add-ons are do-not-buy, (2) the buttons to navigate to the next screen are clear (not swapped, minimized, etc). But that may have just been my settings / environment?
