In the last 2 years, Wikipdia's quality declined. For me this was evident when they suddenly changed the UI. The new UI is more annoying. Perhaps it is nicer for Average Joe people, but for powerusers it is just annoying to use now. But this is not the only problem: many articles have a low quality, or they are so complicated that Average Joe doesn't understand them, which is ironic considering the UI was most likely changed to appease Average Joe.

I am also displeased with the constant pop-up or slide-in widgets. This is a general curse for browsers that ublock origin prevented. I hate this. My browser should not allow for any such slide-in banner. I am never interested in anything written there - usually it is a "gimme more money", but even if it is not, I simply don't CARE what is written on it. Even python used this, on their homepage, where they are even so cheeky that you can not fully disable this thing, unless you block it with ublock origin.

I feel that too many websites fail the user now. Wikipedia does too. The intrinsic quality is still better than the AI slop spam that Google amplified world wide, while also ruining Google search, but the quality used to be better in the past, on Wikipedia.
