Easy. You end up with accumulating evidence showing that it is difficult to pull off surfaces in normal cases, and from contact tracing with the vast majority of spread explained by droplets. As evidence accumulates, people get less and less worried about fomites. And I'm sure that not all came to the same conclusion. You can probably find some that think 5G is a major contributor. But a broad consensus forms, where people start to think of surface sterilization as somewhere between "not important at all" or "only mildly important" as a measure to prevent COVID spread. But the precautionary principle means, until the evidence is in--- maybe using protective measures that are effective against other viruses is a sane thing to do until we know more.
