So? This seems like a thought-stopping word: "Oh, gatekeeping! Awful". I'd say we could use some more gatekeeping.

Well, if you mean the blind, or even people with no time outside car commuting, etc, well for them it's another matter.
I might rely on a walker to go around, but that doesn't mean that it's just an altertive for walking that I prefer, as opposed to a remedy for a health issue.
My sense is that when people talk about gate keeping there’s necessarily an emotional component. In this case I’d guess perhaps there’s a sense that “reading a book” is valuable or prestigious and they don’t want to exclude someone from it.
But to me it’s just an observation of how you consumed content, free of emotional charge.
