Risk probabilities also need to be taken into account. The science on mask wearing did change and it's possible it may change again if the virus evolves in the near future.

What won't change is the risk profile of wearing vs not wearing a mask. Wearing a mask despite necessity is an inconvenience, but unlikely to result in harm. Not wearing mask, even if current science says is safe to do so, is still exposure to potential harm that may have been unforeseen. For instance a transmission vector that is not yet a well characterized one. This is why I personally take a dim view to these sorts "following the science" arguments.

I'm not opposed to erring on the side of caution where things are evolving fast and we may not have enough good science. What I'm opposed to is making political statements like this because it can easily backfire, especially when society is already very polarised.

Agreed. Although sometimes its easier not to fiddle with the mask taking it off and on again, especially if one doesn't have easy access to hand hygiene
