It doesn't matter to you in the sense that Tesseract is a web browser frontend and if you use Voyager you are not personally affected by the block list in your consumption of content.
It may or may not matter to you in the sense that your posts and comments might be silently shadowbanned and hidden from a lot of the people who do use the Tesseract frontend. And if you are not personally on the list, some people whose content you care about may be.
It also may or may not matter to you as a matter of principle, in the sense that you may care about the issue of silent censorship.
