I interpreted the author's stance on opinions differently. I believe he meant that having a strong opinion on tools and architecture is a signal. A signal that the developer is battle tested, been there and done that, and have the scars to show for it.
When I read the bit about having strong opinions, my personal reaction is to recall when my team(s) wanted to ditch SQL Server for first MongoDB and then later CosmosDB. I physically felt sick.
