>>61347166she made the wrong move but not for the reason you suggest
"i can't speak english" is merely your run-of-the-mill kiddie spam, just like how people spam "fubuki is a cat". there's not that many ID viewers who are legitimately angry at Ollie speaking english, at most they'll just move on to other streamers.
what Ollie did here showed a moment of weakness where she allowed those spammers to get under her skin. that's never a good look.
