Gay people don't have to, and often don't, vote based on LGBTQI organization recommendations.
However, if LGBTQI organizations believe that LGBTQI people are more impacted by gig work, shouldn't the orgs be speaking on that?
It seems relevant to me. As long as dismissal for being gay is still possible, workers' rights seem to be very much in scope for these organizations.
[To downvoters: What's the point of having an organization, otherwise?]
