You really do not want to be explaining Javascript to my mom and pop, or most othersSadly, my mom doesn't go clicking around in the options dialog, no matter how much I encourage her ^^ Hardly in my presence, not ever in my absence.
But even if it was otherwise; explaining that "this needs to stay on or many websites won't properly function" while pointing out the options she might want to change, would be enough? I mean, you don't even have to understand Javascript to code in it, much less to be aware of the toggle... ?
We have roads with cars on them. People can walk into those roads, but don't. For many reasons, but none of them a deep understanding of biology or physics. If we fenced in all roads, we would avoid some of such accidents that are still happening - but would also raise people who need the fence from then on, because they're used to "wherever I can walk, there is no danger of being run over".
And yes, this also means looking someone who lost their child who ran into the road in the eye, and saying "I'm sorry for that, but it's still worth it to not fence everything in." Are we too squeamish for that? Since when are coders so scared of user complaints based on ignorance or using the software wrong? Don't those come with the terroritory?
