I would say that for me, the personal preferences plays main role in choosing tools. The choice of the tools you work with depends on your business and what you want to reach as well. I always choose technologies which best suits to my goals and I can easily get efficient results.
Everybody’s free to use the tools which they prefer. They have the right to use the technology which perfectly can solve the issues of their individual work and be an appropriate supporter. But when working in a group we all must respect the desires and preferences of the others. The team must discuss the best tools and technologies for their business, project or ect. And finally, they must pick the best ones and use them.
As a technology steward I would proceed as I do some investigations on the technological needs of our project goal or business and the technological needs of my team. Based on the main needs and the wanted results, I would choose the technologies which can easily and more succesfully support our goal and provide us more efficiency. Then carefully I would discuss them with the others and put them into practice.
Looking at the preferences and perspectives of the others would give me some new knowledge for a technology. It would provide me a new point of view of working principle and other opportunities. But I do not really think that it will change my view as tech-steward. It is because I best can choose the technology for my goal.
