Author of the post here. The r/netsec community brings up good points. One thing that's come up frequently is the question of trademark disputes. Handshake does have mechanisms in place to protect a good number of existing trademarks (only the domain owners of the top 100k Alexa domains can register their names as TLDs), and it also has mechanisms to prevent early squatting through the 52 week period for name rollouts. These mechanics protect trademarks in the short term, but in the long term anyone can bid on an unregistered name in the open auction system that Handshake created. My perspective on this is that there isn't an inherent reason why a naming system needs to deal with trademark issues — there are pros and cons to names being registered in an open auction, just like there are pros and cons to Bitcoin being a store of value that's difficult to censor and seize.
