Opinionated piece with no substance or analysis, author already has some answer in mind and is trying to spin everything around to support it.
Just to illustrate:
That’s why Zuckerberg bought Instagram: he had been turning the screws on Facebook users, and when Instagram came along, millions of those users decided that they hated Zuck more than they loved their friends and so they swallowed the switching costs and defected to Instagram. In an ill-advised middle-of-the-night memo to his CFO, Zuck defended spending $1b on Instagram on the grounds that it would recapture those Facebook escapees:
In this very link, in court-released emails Zuck states they’re buying Instagram because they have good growth and Facebook mobile usability is shit. It’s just 2 different types of social networks, back in 2012 you couldn’t even DM on Instagram, it wasn’t a replacement for Facebook by any means and vice versa. Zuck was just not happy that people spend their phone screen time outside of his reach.
It’s been production-ready for a while, Valve is known to use it for long time. Official release is more for API and ABI stability so you don’t have to change anything to upgrade.
