Yes, many of the "tweakers" discussed did achieve success in multiple business ventures (and took patents).
It's not a disparaging term, so there's no reason to call it backlash. This is simply an observation that there is a (often overlooked) class of people who are 1. technically competent 2. very good at polishing and perfecting others' ideas, rather than coming up with them de novo.
The paper credits these people with playing the main part in the Industrial Revolution, and it's actually quite creditable to say Steve Jobs might have been among the best of them.
History will judge.
