In the early days of FB, they convinced people that pages (or some content, sorry I do not know the FB terms) could be public for anyone to view without needing to login to FB. This was very helpful for small businesses and communities. In many countries this is still the quickest place to make a public page. Though now, every small business or community page I want to visit is locked out unless I login FB. Even if I do login it is impossible to copy paste the important details of a page or post, plus the UI is as ugly as it has always been.
I am currently in the USA and when I visit a public FB page e.g. [1], there is a small login header, and a very big annoying footer login. I estimate 15% of the content is blocked. I had spent the past year outside USA until one month ago. When I visited the same sites while traveling outside the USA, the annoying login footer moves to the middle of the page blocking almost all content. I do not have proof at the moment, but that was my experience trying to read 95% of government, business, and community pages who are almost all on FB.
