美国硅谷的内部人士告诉 BBC ，社交媒体公司故意让用户沉迷于他们的产品以从中获取经济利益。
Aza Raskin from the Centre for Humane Technology said social media companies deliberately use addictive technology in their apps in order to lure us in to spending as much time on their platforms as possible.
Aza Raskin invented the endless scroll – the app feature that means you don't have to click to get to the next page and can keep scrolling for far longer than maybe necessary or healthy.
Aza says he did not intend to hook users with it but says the business model of many social media companies is designed to maximise user time online. He says this encourages designers to come up with technological tricks that hook users.
Sandy Parakilas, who was a platform operations manager at Facebook in 2011 and 2012, said there was definitely an awareness that Facebook was habit-forming when he worked at the company.
桑迪·帕拉吉拉斯在 2011年和 2012年间担任脸书的平台运营经理，他说他在任期间，公司内部确实意识到脸书容易让用户上瘾。
Facebook and Instagram have told the BBC that their apps are designed to bring people together and that they never set out to create addictive products.
