I think blockchain domains are detrimental to the existing system, so I don't get why XYZ would help try to legitimize them. They're not even promoting XYZ. They're literally encouraging customers to go buy a .eth domain where XYZ doesn't have any control or make any money.

It's probably well intentioned and I like seeing XYZ making an effort to do more than maintain the status quo, but there are better ways to promote domains than jumping on the blockchain bandwagon in my opinion.

XYZ has become a common go-to in the community so it seems to be working well for them.

Ponzi schemes are the reverse of interesting.
