I agree that text formatting should be accomplished with Markdown if at all possible. Since Markdown is used across Stack Exchange, there will generally be better support for proper rendering across browsers, mobile devices, screen readers and other accessibility tools, and better compatibility with future systems. MathJax, by its nature and because it is ...

I think the question is too emotionally laden to present the problem correctly. To me it is like "All the preprints use Knuth's computer modern font. How dare we change that?". The use of the word 'abuse' seems to have already not only judged the action, but tried and convicted it, and sent a summons to the executioner.
A more charitable presentation ...

Especially for more complicated diagrams (where it's difficult to draw them using AMScd), a possible solution is to use presheaf website and include the picture into the post. I have learned about this site from Bruno Stonek's answer to How to draw a commutative diagram? (Mathematics Meta).
Advantages of this website:
It is easy to use for people who are ...

Once typographers are allowed to run amok, there is no way back to normality. For it'd be only a question of time for multi-coloured flashing parts of text, and what not, to start to appear.
Contributions to MO are akin to papers in a journal or chapters in a book, where the editors are free to impose a uniform typography style.
Are there any Markdown MO ...

The problem is caused by the fact that if a comment contains many consecutive characters without a space, the Stack Exchange software inserts invisible unicode character (\unicode{x200C}\unicode{x200B} Zero Width Non-Joiner, Zero Width Space). in the comment.
There are several posts on Mathematics Meta with various suggestions what to do when this problem ...

This is a community wiki answer intended as a place to collect examples of posts and comments which are examples of the described problem. Feel free to add further examples if you find some more. (But let's restrict this to examples where the problem was caused by the recent software change described in the question - not those posts/comments where the ...

To the best of my knowledge the only type of commutative diagrams supported by MathJax is AMSCd.
Some info on commutative diagrams can be also found here: How to draw a commutative diagram? There is also this feature request: Can we support TikZ picture rendering? (Both posts are from Mathematics Meta.) There is also a feature request related to xypic on ...
