Bad analogy. There's a difference between that, where the hypothetical car in question has malfunctioned, and a company being able to just decide that a feature that they offered across the board for free is suddenly being discontinued. Imagine that you have a Ford that comes with seat heaters. You've been able to use those seat heaters, at no additional charge, for several years. All of a sudden, Ford decides they want to make existing customers pay for something they've been using for years. The next time you go to the dealer for an unrelated reason, they silently install Ford's new update that restricts you from turning on the seat heaters without paying a monthly subscription to Ford. Even this analogy breaks down, as with the Arlo situation they have to provide server-side storage for the feature, whereas such a seat heater conundrum would not. However, this analogy is closer to the real situation than "manufacturer stops making parts three decades after discontinuation".
