Except markdown is not easier to read if you clutter your comment (as I've seen other commenters here do) with something like:
```
foo
bar
baz
```
```
note all the
extra
vertical
whitespace because regular paragraphs get a slight
gap
```
```
let's
throw
in a
third block
for some reason
```
As code blocks:
foo
bar
baz
note all the
extra
vertical
whitespace because regular paragraphs get a slight
gap
let's
throw
in a
third block
for some reason
The former becomes a problem in the discussion because it clutters the space and is harder to read than the latter, especially when you have multiple blocks around the discussion (in one comment or spread out across comments). You may not care, but using code blocks that offer a more compact and clear expression is certainly more courteous.

I disagree, and so it's not likely "certain".
I do think that nitpicking over formatting is rather unproductive and rude, though. And it had wasted considerably more space than a format that you happen to dislike, but that others are fine with.
Like I said, I don't care. If you do, then that's on you.
I also disagree about not using ```. It's useful when writing markdown in an interface that swallows whitespace.
