There are similarities, just exchange lung cancer with suicides among teens. Big Tech must take its responsibility more seriously and not pretend it's not their fault.
The difference is that smoking is clearly linked with lung cancer, established by heaps of clear scientific data. The link between social media and suicide is pretty weak by comparison.
You and the author are both lumping all of Big Tech in together with Big Attention-Exploitation.
The latter is the subset to which people’s ire should be directed.
Amazon and Google are hardly innocent players. One could go on to point at the effects of Uber, Yelp, AirBnb, Palantir, so on... all "Big Tech".
