Arguably in this case the domain squatter did provide some value to society. The thing with squatters is they are always willing to sell for the right price. Other types of domain owners are not so predictable. In particular, domains with established businesses are unlikely (I'm guessing) to sell for anything less than the value of the entire business, even though that business may be less profitable and less value-adding than a business proposed by a potential acquirer of the domain. If the domain was squatted instead, the less profitable business may not have bought it at all, leaving it for the more profitable business.
In this case, the domain squatter may have contributed some value to society. Squatters are typically willing to sell domains for the right price, unlike other domain owners whose actions are less predictable. For example, domains tied to established businesses are unlikely to be sold for less than the full value of the business, even if that business is less profitable or less impactful than what a potential buyer might propose. If the domain had been squatted, the less profitable business might not have acquired it, potentially leaving it available for a more profitable or innovative venture.
In this situation, the domain squatter may have offered some value to society. Squatters tend to be open to selling domains at a price that appeals to them, unlike other domain owners who can be less predictable. Specifically, domains associated with established businesses are unlikely to be sold for less than the complete value of that business, even if the business is not as profitable or as beneficial as a proposal from a potential buyer. If the domain were held by a squatter, the less profitable business might not have pursued the acquisition, leaving the opportunity open for a more profitable venture.
In this case, the domain squatter might have provided some benefit to society. Squatters are more likely to sell domains at a price they are comfortable with, whereas other domain owners are less predictable. In particular, domains that are related to well-known businesses are not likely to be sold for less than the full value of that business, even if the business is not as profitable or as beneficial as a buyer's offer. If the domain was squatter, the less profitable business may not have tried to buy it, and the more profitable business could have.
In this case, the domain squatter may have provided some benefit to society. Squatters are usually willing to sell domains at a price that suits them, whereas other domain owners can be more capricious. In particular, domains linked to established businesses are not likely to be sold for less than the total value of that business, even if the business is not as profitable or as valuable as a proposal from a potential buyer. If the domain were occupied by a squatter, the less lucrative business would not have gone for the purchase, and the opportunity would have been available to a more profitable business.
