It’s very reasonable to implicit read that meaning into the question. Like if I am at a dinner table and ask “how is the turkey” I reasonably understand that only the people who are eating the turkey would answer. I don’t have to say, “for those of you who are eating turkey and have taken a bit, how is the turkey”. This is doubly true for social media where everything is a mass broadcast.
Then OP should have posed the question like this:
“Those of you who are still on X despite Elon Musk’s antics, why?”
