It depends.

If someone is in active recovery, they may exactly know what they can handle at that point. For example, someone who had sexual abuse in their history knows they don't need to see someone else's depiction. That's not going to help them face and overcome it and will more likely set them back for the day. If they're going into an R rated movie, the trigger warning is right there in the rating system. That's not the case for all media.

Or, it might be that on some days they can handle it, and some days they can't. I don't always want to hear about religious trauma because I already have that T-shirt, but on other days and in other contexts I might be curious.

I appreciate trigger warnings though I don't need them anymore.

Unfortunately, my brain has a fairly strict rate limiter and I have yet to see a way to pay out of that.

I would like to point out that Linus is against forking the kernel, and his group essentially demands a unified kernel and toolchain (with different distros having different configurations of these pieces).

Torvalds's copy isn't deployed by most people. Red Hat does its own fork (or patchset), as does Ubuntu. TiVo certainly keeps its own copy. Andrew Morton has gone on record saying that a competing fork would be impractical, but I haven't seen anyone "against" such a thing.

If someone really wants to create a dependent sound system, I'm sure Mark Shuttleworth would like to hear from you if you can make the experience better.

Frankly, for most people, they can just use Ubuntu and forget about every other distribution on the desktop.
