I think the original question is valid here - I also don’t get any right-wing ads. I guess that is because I never interact with those kind of post, also not negatively, exactly BECAUSE I want to see less of them.
Twitter still allows you to mute/block any advertiser… I’ve seen fewer big companies that make a million throwaway accounts for advertising to make it hard to mute. Any ad account I notice more than a couple times gets muted, Twitter asks me if I want to upgrade to paid and I ignore that.
