(Ill reply to both parts in separate replies)

Subtitles/dubs are translations. They adapt language, not pacing, cinematography, editing, or structure. That’s fundamentally different from altering a game’s difficulty, which changes the mechanics, the thing the art is built from and differentiates it from other mediums.

A better analogy:

• Subtitles are like adding glasses so more people can see the same painting.

• Easy mode is like repainting sections of the canvas so it’s “clearer.” You can call both “accessibility,” but one preserves the work, the other mutates it.

Furthermore, language isn't a good metric by which to compare analogies because games are also translated.
