I did not get this on Firefox mobile using uBlock and JavaScript disabled.
I was able to read it perfectly while using uBlock.
no overlay here on fennec + ublock.
Reader mode also available but not even needed.
interesting, on brave such popup never came up.
Brave is automatically using some list to disable "cookie banners". The kind of thing that you need to manually turn on in uBlock.
So the people on Hackernews with adblock aren't reading this.
