I tend think it's systemic of tech's new culture that's stuck in a feedback loop with itself. The recent tech culture seems to stem some huge fallacies about what it takes to be a "good" programmer and the agenda is pushed by all the tech companies and charters.
For example, participating in hack-a-thons, commiting to open source, blogging, tweeting, working on personal projects during the weekend, updating your linkedin profile, participating in hacker news, etc...
Moderation is key and life is a trade off. So the extra time spent working is your life slowly being wasted away for some other persons benefit for free.
Additionally, a lot of start ups believe will change the world, they won't. Your tee shirt or food delivery business aren't going to change anything, but for someone reason, they sell to their employees these lines and they believe it.
The pressure to confirm and turn yourself into a model programmer seems more toxic then anything else.
