I've noticed a shift over the last while how privacy-protective people are becoming "out-group" and a little weird.

I mean, I personally don't care; I've always been a little weird. But it is funny to see technical preferences as a signaling mechanism.

Funny, that is, until it hits a certain point... http://www.wired.co.uk/article/chinese-government-social-cre...

I have started using a "Quick Javascript Switcher" extension some years ago to easily opt-in for certain pages but have js disabled by default.

This was one of the best quality of life decision in terms of web browsing I have ever made.

The vast majority of pages that I randomly access (e.g. from hacker news) are text based and usually work just fine without js. But the time until I can start reading is much faster (less jumping around of content) and I don't get the growth hackers modals shoven down my throat two paragraphs in. The pages I use regularly are usually white listed

Yep, a cheap way to minimize ads, tracking and browser exploits.

Also avoiding downloading JS libraries bigger than Quake while on the go.

It's more common than you think.

Only on Hacker News :)

Flash fully disabled in this day and age? ;-)

More like "disabled by default," actually. It's mostly ads/tracking, popovers, and other annoyances, and it's easy to selectively turn it back on where you really need it. This approach isn't for the general public yet.

No page shows JavaScript for me until I enable it with NoScript. It's too sad that Firefox Focus on Android doesn't allow plugins or disabling JS, it make it makes the whole thing pointless.

opt-in rather then no opt-out?

I fully disable it.
