For my comment to be a "false dichotomy" as you claim, I would have had to suggest that Reddit having stale, regurgitated, copy/paste comments is somehow related to or even caused by it being an issue on Twitter. I didn't.

me: This thing makes Twitter unfunny.

you: As opposed to Reddit [...].

P.S. You may want to revisit your understanding of what a false dichotomy is.

a "false dichotomy" means "because A, B results" when one A doesn't necessarily have anything to do with the other.

Wrong. A false dichotomy/dilemma is a type of informal fallacy in which something is falsely claimed to be an "either/or" situation, when in fact there is at least one additional option.

For example, "If you don't support Donald Trump, you're unpatriotic." The first clause doesn't conclude the second.

That's pretty much the definition of a non sequitur, not a false dichotomy. An example of a false dichotomy would be: "if you're not a Republican, then you're a communist".

Again, no.
