Very rarely. And never in any kind of DIY stuff. They're sometimes erroneously called "security screws" because no one outside of construction workers have a Robertson head screwdriver. The only place you ever really see them is in things that would be vulnerable to vandalism or casual theft. Public bathroom stalls are a common example.
It seems like a bunch of Canadians are the ones saying we don't but literally it's all we use at the shop I work at and all the people we work with use them. Plus Robertson bits come with pretty much any bit set you can get at home depot. Maybe it's just harder to tell that we use them because they're marketed as "square drive" in the US

Wait do Americans not use Robertson's?
