I use uBlock Origin + vaft from TwitchAdSolutions, which is currently working pretty well for me. I’ve had some issues before, and every now and then the stream can freeze up when an ad is played. But it’s so much better than having to endure even a second of those mind-rotting ads.
When you say “trans woman” you affirm that they are women, and trans is just an adjective. When you say “transwoman” it can imply that they are something different altogether, and TERFs have certainly used it as such. Like, I dunno, a carpark isn’t a park? That’s the first example that came to mind, anyway.
