That article is bullshit. You can't judge gov.uk by its homepage, because that's almost never where you land.
Now that we have gov.uk, whenever I google something about doing my tax, or registering to vote at a new address, or any other arduous governmental admin shit, I usually end up on a beautifully simple and focused gov.uk page, and I'm in and out in 2 minutes. That's what a government website is about.
Look at how brief and clear the writing is. Look at how straightforward its URL is. Have a look at some more pages, look how consistent the design language is. This is exactly what a government website should be like.
