Well, it seems like the distinction in the cases is not the amount of technosolutionism but the amount of government backing, no?
Quoting the article on that precise point:
> Critics of the technosolutionist approach point out that contact tracing apps, which were quickly embraced in countries like China and South Korea, were effective only if public health services were also able to successfully test the majority of people at risk, something that has yet to occur in the United States.
Technology is a necessary component of many solutions, but is rarely per se the solution. The old internet saying "There are no technical solutions to social problems" comes to mind - it doesn't mean that technology can't contribute to the solution (many social problems have solutions that require statistical models, cookies, higher-performance internet connections, Spanner, whatever), it just means that the technology doesn't solve the problem on its own. Wikipedia, for instance, would not be what it is without the wiki, but it is certainly not simply the wiki - it's the decades of writing that happened on the wiki.
Many people set up their own wiki, in the wake of Wikipedia, hoping to see the same success. Very few of them ended up working.
Technical-component-of-a-social-solution-ism is not technosolutionism. The article defines technosolutionism as follows: "Technosolutionism is a way of understanding the world that assigns priority to engineered solutions to human problems. Its first principle is the notion that an app, a machine, a software program, or an algorithm offers the best solution to any complicated problem."
All the projects from March to build 3D-printed ventilators at home, for instance, were technosolutionism. There's a lack of a physical item; we have 3D printers. Obviously we can 3D print our way out of the problem!
I'd argue that https://www.vaccinateca.com/ , for instance, is not technosolutionism in the definition above, despite it relying on a website and Airtable (https://twitter.com/patio11/status/1350539166296100864), because they're not saying "We can build a platform for pharmacies to enter data," they're saying "We're going to call up pharmacists, ourselves, and type what they say into a spreadsheet." Of course there's a lot of technical work that went into Airtable. But the difference, I think, is that they set out to solve a problem, and along the way they found a place where technology can help; they didn't set out to find a use for technology.
