The things you’re describing are not science. This might seem nit picky but the scientific method as we know it today require that peer review and require methods of reproduction. Whether you can reproduce results is a different story.
The entire difference between research and science is whether or not you engage in the process of peer review and review often requires method of replication. So you usually can’t have one without the other. If you aren’t trying to have your paper reviewed by your peers, that’s fine, but that isn’t science.
To address the gatekeeping, I get it. We shouldn’t be using the word to demean people who do valuable research but don’t strictly engage in the scientific process. That’s really not important to do. However we should all be interested in preventing the scientific process from being muddied to include every R&D process under the sun. That’s all research, not science, and we call them separate things for a reason.
Oh yeah strictly speaking if you follow the scientific method you are doing “science” however what the twitter thread is getting at and what I’m getting at is that science without the scientific process isn’t the same thing. Typically in a professional setting we just call that research.
The scientific process contains the scientific methods but there is an aspect of connection to the scientific community. I’d argue that if you’re using a company to build and develop a working base of knowledge through the scientific method, you’re failing at the building and organizing knowledge part of that science definition by not sharing what you know.
