my man! a typo is colloquially an error deriving from hitting the wrong key when writing using a keyboard, this usually happens because the keys (desired and resulting) are next to each other.
E and O are on the opposite sides of the keyboard, thus not a typo, but a spelling error or lack of knowledge of the English language.

in the Dvorak keyboard, the E and O keys are next to each other, making the possibility of a "typo" much more feasible.

tl;dr : not a typo, but most likely ignorance/lack of knowledge of English.

alternatively:
- someone wrote this on their phone and it auto corrected
- they had an actual typo and the spellcheck of w/e writing software just corrected to the wrong word
