In a previous job we had a small office with just 4 toilets. About 10% of employees were female. There had originally been 2/2 male/female toilets but that was changed to 2 male, 1 female, and 1 unisex toilet. That worked well in practice.

So I agree that unisex toilets can be a good idea, but it's a different matter to protest against binary gendering on toilets. I wouldn't like to work for a company that partakes in politics.
