I would rather say it’s “predictable”, rather than “understandable”. Perhaps even, “no better than we can expect”. Calling this “understandable” tends to normalize greed for greed’s sake.
The hate for successful people here is ridiculous. Neither Discord nor its investors owe you a world-class service with private servers, video calls, screen sharing, voice calls, and many other features for free. The market operates on mutual benefit: you get the service, and the owners get the money. Those who complain about businesses aiming to be profitable are lunatics.
This isn't hate for the investors, but for what they've pushed for. Discord was already profitable, this is just driving enshittification; per the article.
