These people shit on accessibility because they see it as something that other people need, not them. The attitude is that if you aren't good at a game you simply shouldn't play. It's fundamentally a lack of empathy.
My go-to argument when people take that stance is to ask "Do you think you'll still be playing games when you're 50? When you're 60? When you're 70?"
Their answer of course is invariably yes, they will, and so my follow on question is "Will you still have the same lighning reflexes then, that you do now?"
That usually gets the point across.
Right now they can look down smugly from their pedestal, but some day there will come a time when their own body fails them and they can't make it through Dark Souls 12 anymore, no matter how much they enjoy it and want to finish. And when they complain on Steam all the kids will say "just git gud lol"
Who's the one crying then?
Accessibility options are important for all of us, no matter the reason. We should all get to choose.
With TV there were only so many channels, but with Internet distribution the limits have been blown away on how many shows can be produced and available at once. There's more content now than ever before, and the way people consume that content has changed, too.
Streaming incentivises a model where new content is pushed at you constantly to keep you watching and "engaged" (because engagement = ads = money) and so the most important metric is quantity of shows, not quality.
I've watched shows I enjoyed that six months later I couldn't even tell you the name of, because it's a once-and-done watch, and then I'm onto the next thing.
With such high volumes of new content there's no opportunity to get bored anymore, and that has consequences for how much old content gets revisited.
In the 2000s we'd all have some series or other on DVD, and when there was nothing good on TV that night we'd go back and re-watch it. And that re-watch process built up both your own personal fondness for the show, and the staying power of that show in the shared cultural consciousness. Plus you could probably speak with your friends about shows because chances were pretty good they'd seen it too, which only boosts it more.
When we're all just watching things once and never again, and often not even the same things as each other, there's no staying power.
I also believe - my personal opinion - that this quantity problem is why right now there are SO MANY remakes, reboots, spin-offs, and live-action versions of existing movies. Even the big players are finding it very hard to launch new things that reach the audience they want because the market is so absolutely saturated with "content". And so they have to fall back on franchises that are already recognised and popular across a wide cultural gamut, things that cemented their popularity at a time before the quantity problem really set in.
It's strange times.
