No, I think if something can be done to allow more people to enjoy the game, then it should not be considered a bad thing to do it. You can not make it accessible to everyone in the world, but if there are time and resources to add accessibility, it should not be neglected.

And I don’t agree with the use of artistic intent as an excuse to not include specific accessibility options: take closed captions for example, they are made to allow deaf and hard of hearing people enjoy the content even when they can’t hear the sound. A lot of media is built on sound being a cornerstone of the experience, and people who will use closed captions will have no notion of it, but does it mean that they should be excluded completely?

Just because people who use the accessibility options will not experience everything in a way the author intended does not mean they should not be experience it at all, and in this day no one really complains about game including captions or colourblind options, but anything that might affect difficulty is, for some reason, out of the question and is only subject to the artist’s vision of it.

Easy mode is not fake accessibility. Celeste has the correct idea in allowing players adjust the difficulty for accessibility purposes. Not everyone has the same reaction speed, same cognitive abilities, same eyesight. There are people who can only use one hand and that automatically makes reacting to attacks many times harder, should they be excluded from being able to enjoy the game because they are not physically capable enough for the boss fights? And boss fights are probably 5% of the game anyway!
