I think its a fair assumption here on hacker news, that most users are creators rather than consumers. And as such, the piece of software they "would never use" is very likely one they (or one of their peers) wrote.
I don't think it is a particularly good look to write adtech by day and run ublock by night, but even more than that it is also hardly sustainable. The custom solutions we run in our ivory towers and don't share with the plebes get harder and harder to create on bad, locked down platforms we help build for "them".
And I also think the assumption, that when it does not serve us, it serves them well, is also a false one. They may not know better, because they are not creators, but I think most folk have realized that computers and software often acts against their users interest.
So, who is supposed to change this, if not the people who have the knowledge and do actually build these systems? Just saying "I use something else and its their fault for not doing the same" does only make us accomplices in making the world worse for all.
