But also > You can paste source code directly into your Markdown document without any changes, and it will appear as expected in the rendered HTML. That’s my doing.

In that sentence, it kinda does sound like they're trying to take credit for it.

Its upon the reader to ascribe malintent. Ill choose not to.

Generally I don't like to point out typos, but in the context of malintent: Ill vs I'll is pretty amusing :D

There is an entire article. There doesn't need to be just one sentence plucked out of context.

"I pointed this out in the Markdown mailing list, and Gruber agreed that it should be changed. In the next Markdown release—which was, I believe, his last—he made the change, and all the text in code blocks has been treated literally ever since."

What's wrong with that? He said what he did, said who fixed the issue, and stated the result.

It is their doing - they started the series of events. It's other people's doings ALSO. This sentence doesn't imply exclusivity, it just doesn't say others did stuff. Fortunately the entire rest of the document, particularly the part I highlighted above, makes it very clear:

1. what their doing is in more specific detail

2. what others' doings are in more specific detail

I'm going to assume that the author included all that additional detail in the document on purpose, and with the intent of clarifying what "That's my doing" entails. It seems pretty unlikely that your hypothesis of "the person is claiming the whole thing is their doing and accidentally wrote a whole bunch of words undermining that simple sentence" is the right one.

Or maybe the reader can do better than isolate a sentence out of context and assume bad intent. It’s obvious this is not to be taken seriously. It’s a few paragraphs on a blog, FFS.
