I thought that the first amendment was about people rather than companies. In addition to that there are many products where companies have to display certain information, such as age rating for games, health warrnings on cigaretts, food content, allergy warning, nutrition labels, medicine side-effects, etc
It is hard to classify censorship as speech for a site that it is all about user-content.
One of the "open source" licenses that it is under is LGPL, you can do whatever you want with your code. (Although this does not mean that you should, please avoid publishing closed source software)
I hate this. If I know the password I should be able to log in to my account no matter what (unless if I have 2fa enabled). Sadly companies like Google and MS do not like this idea, they also often use the excuse that they can't verify you in order to mine your phone number.
"Edit: Account recovered. I used chromium to login (which I never do) and then back to Firefox"
How can google keep getting away with this? MS got into trouble with IE with much less.
"Note that any data can be transferred over HTTP(S), including, on occasion, either compiled or uncompiled LaTeX."
Sure, but I don't see what this has to do with anything.
As for your perception, I don't care :)
Keep it to yourself next time please. You too are being perceived in a certain way as well but telling you how would likely be against this site's rules.
To respond to your question: no. Not sure why you linked me the PDF 2 specification. PDF/UA is from 2012, and the ability to tag PDF files for accessibility is a thing since 2001 (with PDF 1.4).
Various tools and packages that attempted to generate accessible pdfs from LaTeX have existed for aeons, all of they had a common characteristic: they sucked. I am convinced that by this point everyone who cares about accessibility has moved to other formats (like HTML).
Don't make assumptions about me. A LaTeX document is also virtually never directly consumed by web browsers.
In addition to that we are considering LaTeX for the web, not DVI, not PDF, not something else that you compile LaTeX into.
And well, given the amount of people that use overleaf I would say that a lot of people (although writers instead of readers) consume LaTeX.
(Btw, you can compile html too, try printing it as ps/pdf document)
"must"? A web4 browser would probably use a "runtime compiled" implementation.
"Whilst that may still pass poorly-structured documents and result in poorly-formed output" - this by the way happens much more often with LaTeX compared to html in my experience.
I honestly don't see any advantage to LaTeX over html+svg+css+mathml+??? for any usecase. Everything that LaTeX does the things that I mentioned do better.
