I think the author is using "ableism" when they mean closer to "elitism" - primarily being about level of commitment and expertise.

Often these goals do align - like how making clickable elements more obvious helps new/casual users and also those with visual impairments - but I don't think it can reasonably be called ableism to oppose obscuring a configuration option. In fact, since it's likely those with some kind of unique situation who depend on the options that the majority don't, I feel the accusation of ableism may often make more sense in the other direction. Though realistically I don't think either accusation would helpful in a conversation weighing up benefit and maintenance burden of keeping the option.
