Same here, I only follow tech and creative people doing work that's relevant to my interests and unfollow at the first whiff of unrelated political topics. The only problem with this approach is that you do have to unfollow a lot of people to make it work (or be invested enough in the good stuff on Twitter to sift through a timeline full of garbage looking for it, which I am not). For some of my interests, like infosec, I can't really follow anyone because it's just the norm to use your professional account to broadcast your uninsightful pro/anti/smugly aloof views on the hot US political topic of the week.

I doubt changes in Twitter leadership will change much for people who use Twitter this way. It's unlikely it would be in Twitter's interests or even widely popular but I do hope for better tools for configuring your feed, especially options to filter out politics and current events if that's not what you're on Twitter to read about.
