I don't know about what they actually do because I've never interacted with the company other than reading what they publish. I have to tell you that if you apply the things they share, where previously you had a home-grown "process" or lack thereof, your engineering organization will produce better results and your engineers will be happier. I can't vouch for every single thing they ever wrote, but I think this style of rebuttal must be coming from someone who's had to work in disfunctional places with overbearing product management.
The pendulum can swing too far both ways. Having worked for a startup that consisted of probably half ex-thought workers I can attest that yes some of the development processes and infrastructure we created were commendable. Some others were just absolutely frustrating. However I feel the only metric that’s really worth mentioning is that after a couple of years, there was practically no product to show of, not a single paying customer and the company slowly burned through its entire runway and faded to (more) obscurity. Yes I’m convinced that the ideological stances such staff took were directly correlated with the business failure. I think the only positive result was focusing on building an ivory tower meant everyone’s CV looked more impressive.
