I linked an email with my Reddit account long before it became recommended. Years later, I deleted that gmail account. Even more years after that, Reddit decided (automated) to lock my account until I reset my password for no discernible reason, the only option being via email. It took two weeks with support, across 3 different mediums of communication, to get it reset to a new email account.
I guess what I’m saying is that there is an internal motivation at play to get people to register their email accounts at Reddit, and it goes far beyond reducing customer support time because at present, they are going the opposite way. In fact, had I never registered an email, their automated account locking nonsense would never have triggered, and had I lost my password, their official policy is not to help at all.
If you have a higher than market price, then other players can come in and disrupt your monopoly. If you are selling stuff at a loss to drive other players out of the market, then it is impossible for a new player to get off the ground. The definition has more to do with what is in the long term detrimental to the market's diversity.
