Linus Torvalds, who created the Linux operating system that secretly runs the internet, said he detests social media, including the platforms Twitter, Facebook, and Instagram.

In a recent interview, he called these social-media sites "a disease."

That's strong condemnation from a guy who is well-known for "not polite" behavior on public email lists.

It shows just how little respect social media gets these days.

Linus Torvalds, the creator of the Linux operating system that secretly runs the internet and is the basis for Android, was recently asked what he would change about the tech world that his technology helped create, if he could.

His answer: social media.

"I absolutely detest modern 'social media' — Twitter, Facebook, Instagram. It's a disease. It seems to encourage bad behavior," Torvalds told the Linux Journal's Robert Young.

This is interesting criticism from a man who has often been accused of being uncivil to other programmers on Linux email lists. Torvalds is known as a brilliant, funny, and speaks-his-mind kind of guy who is generally fair-minded but doesn't tolerate fools.

That personality means he's publicly dressed down people whose work, or motivations, fell short of his standards. Years ago, he defended his behavior when a developer from the chipmaker Intel publicly called him out for it and told him to knock it off because it was not only unprofessional but was also driving away newbies and others who wanted to contribute to Linux. He shrugged off the criticism by responding, "People are different. I'm not polite, and I get upset easily but generally don't hold a grudge — I have these explosive emails."

Since then, the open-source world has started to confront how much bad behavior goes on its world with various communities and has adopted codes of conduct. In 2018, the main Linux community adopted a code of conduct, too. And along with that, Torvalds finally said his behavior needed changing. He took time off to "get some assistance on how to understand people's emotions and respond appropriately," he said.

So Torvalds calling out social media for encouraging bad behavior is ironic. To be fair, as one of the most famous programmers, he's been the target of his fair share of online abuse, too. In 2015, he made a cheesy, funny video in which he read aloud nasty tweets about himself.

'If you cannot prove your identity, your crazy rant on some social-media platform shouldn't be visible'

Torvalds told Linux Journal that the internet eliminates all the social cues that are usually part of communications, so "nobody can hear you being subtle."

"It's easy to miss humor and sarcasm, but it's also very easy to overlook the reaction of the recipient, so you get things like flame wars, etc., that might not happen as easily with face-to-face interaction," he said.

Torvalds said the same issues can crop up with email, too, but he believes email is more necessary and often communicating real information, which is not always so with social media.

"The whole 'liking' and 'sharing' model is just garbage. There is no effort and no quality control. In fact, it's all geared to the reverse of quality control, with lowest common denominator targets, and click-bait, and things designed to generate an emotional response, often one of moral outrage," he said.

On top of all that, when you add in anonymity, "it's just disgusting," he said.

"Some people confuse privacy and anonymity and think they go hand in hand, and that protecting privacy means that you need to protect anonymity. I think that's wrong. Anonymity is important if you're a whistle-blower, but if you cannot prove your identity, your crazy rant on some social-media platform shouldn't be visible, and you shouldn't be able to share it or like it," he said.

Consequently, Torvalds is not on any social media today, although he briefly used Google Plus for a while, feeling like Google's unsuccessful attempt at social media was "less mindless" than the others. (Google announced it was shutting down Google Plus in December and began deleting accounts on Tuesday.)

Torvalds didn't get into whether or not governments should step in and start regulating internet companies, perhaps making them more responsible for the content they promote (if not host). Still, having Torvalds give the social-media world a "thumbs down" isn't a good sign for internet companies trying to convince the world that they are the good guys.
