I believe you when you say it mattered to you, but:

1. Your experience is likely an outlier--I'm not saying your experience doesn't matter, I'm saying that your experience and experiences like yours are likely not represented significantly in the data.

2. Other people with outlier experiences may have different needs, i.e. an intervention which improves one reader's experience may make another reader's experience worse.

I did some web accessibility work which involved interviewing a number of disabled clients, and the ultimate conclusion was that we needed to make our site colors configurable. One group with visual impairment needed high contrast, while a few clients with sensory issues were unable to use the site for long when high contrast was used because it was overstimulating. The lower-contrast modes also had issues for colorblind clients, although these clients were less common in the user pool.

In typical American corporate fashion, the entire research results were scrapped when a donor wanted us to use color schemes related to our brand, despite overwhelmingly positive feedback from users on our accessibility configurability.
