At previous corporation, the tech lead simply recommended for sackings a developer who was questioning his approach. Once he got sacked, everyone listened...

...and then most of best skilled people left in the following weeks.

Tech lead then hired his mates and company nose dived.

I met that exact kind of leader once. In my case, they also tend to work more on their personal brand rather than the company, and keep ship-jumping every couple of years to spread their gospel.

In most non-IT corporations, the managers are non-technical and most are idiots these days. It comes from the MBA hires getting in management roles where they don't understand the area, what Steve Jobs calls "bozos" in his interview (available online).
