I think you are spot on. The CDC taking mask requirements away for vaccinated people is a not-so-veiled attempt to incentivize getting more people who are on the fence vaccinated. I'm sure the decision was made, at least partially, because vaccination numbers have declined sharply across the country. Those who have made the decision not to get vaccinated have now dug in their heels, and it is likely that many of those were already defying mask requirements, as it is extremely hard to enforce those anywhere. But there is probably a group who are still taking the mask requirements seriously, and may very well see this as the last step they need to do to basically shed the mask and return to a more normal existence. Last weekend I went shopping at Walmart, and for the first time in over a year, I didn't wear a mask. Walmart suspended their mask requirements following the CDC announcement last week, and there is no longer any signs asking for mask wearing or an employee stationed at the entrance checking for masks. And I would bet that, at least in my local Walmart in northern Wisconsin, it was probably 50-50 between those still wearing a mask, and those who weren't. I would also be willing to bet that the majority of those who weren't masked in the store likely also weren't vaccinated. But I made the decision to go without because I've been fully vaxxed and protected since early March. Still, it felt very odd not wearing one ... almost as if I was breaking the law or not wearing pants or something. Masks, while kind of annoying, did provide some level of comfort, at least for me. It's going to take a little while to get over that.
