I still stand by what I said and only add an addendum, all companies enshittify themselves eventually or cease to exist before it happens.
In your counterexample, the problem is that the founders eventually die, and then the time comes for that company to be passed down, and then you are just proving my point. Even stores like LTT Store and GamersNexus’ will eventually enshittify themselves or cease to exist, because they will eventually have to pass ownership and even their owners will feel some remorse if they vanish it into the void instead of leaving it off for their family to inherit.
If it’s a small localized family business, it can exist for longer without compromising itself because it will not receive as much pressure and the services it has to concern itself are much more limited, but otherwise and even then, enshittification is as avoidable as death.
