This is also encouraged by vendors. Old-school "boring" solutions (that you can't rent-seek over) are shunned in favour of proprietary reinventions of the wheel that do the same but poorly or more expensive. This in turn incentivises "engineers" to do resume-driven-development and implement those suboptimal products/services at their own company, and the cycle repeats.
