It's interesting when you think about who this message is supposed to be aimed at. Their hook/USP is their connection to the BRF. That's why they've clung on to the titles and use them in a country which prides itself on being a meritocracy.
If their target audience are the cool liberals, under 50's, people concerned about women's and LGBT rights, it jars using those titles. They're an anachronism and a symbol of a culture that America famously decided wasn't for them. How can you be taken seriously by these people when your profile is based on a title and a fortune courtesy of your Nan?
On the flip side, the people who would be impressed by titles are maybe more likely to be a bit older, more conservative, more comfortable with class distinctions, they aren't going to be swayed by their comments on voting.
I think as time goes on the only thing they have that will give them any credibility is announcing that they're no longer using those titles. And stop suing everyone.
