It's extremely irritating, distracting, and breaks focus on the content instead of the annoying stylistic choice, just an fyi..but I imagine you probably like that this is true and purposely try to annoy the people that aren't in the little club. If not, then I suggest not doing it. The tone I perceive from it is "F**** the reader"
Yes I mean this to anyone repeatedly, consciously fighting natural convention and muscle memory to purposely type every letter in lowercase, knowing that this produces in the reader a slight dissonance and distraction constantly, and choosing to do this instead of using convention that everyone understands so that "syntax" does not become the focus and instead the content of the message does.
Otherwise they're "drawing attention" to the style and themselves for narcissistic reasons. I would simply assume they'd have to know the annoyance this brings to the reader, so I assume it's on purpose.
I would feel the same about someone writing code in a consistently purposeful unorthodox style and against convention in such an obvious and effortful way that no one is used to. Personally, and YMMV, I like to try to write in as clear a way as I can to get my point across as much as possible. Useless stylistic fluff in something that isn't poetry, seems counter to that purpose.

It's not a mistake though to ensure every letter one writes is not following convention and English syntax. Accidents and mistakes are a different thing.

I don't know if you meant to direct this at the person you're replying to but I'm convinced the overwhelming majority of people don't get out of bed in the morning with any of that in mind
It's comments like these that make me reconsider what hateful meanings others might read into my communications or mistakes
