A lot of anecdata in the article, so I guess I'll add mine here: I don't think the Connect process is too onerous, and I don't think any of my managers have ever really brought up the subject of growth mindset except for as it relates to our twice-yearly or sometimes quarterly Connects. YMMV depending on the group and team you're in, but growth mindset is very much in the background for me. And while I do have my copy of Hit Refresh on my bookshelf that I was given, no one has ever used it to push any talking points or corporate agenda. It was really just kind of a PR push.
This article feels like it's making a mountain out of a molehill to push an agenda. Maybe all the people this author interviewed have a particular angle, but the overall "culty" message here does not ring true to me at all.
Also, to be picky:
> Over the coming decades, [Carol Dweck] further refined and defined her ideas, coining the terms “growth mindset” and “fixed mindset” in 2012, a mere five years before Nadella took over at Microsoft.
Nadella became CEO in 2014. At least get the objective facts right, please.
