Fundamentally, anyone can possibly do English, but you need to work on it hard. Some people either don't realize this or can't be bothered to sit down and work on it. Plus the capability is limited up to what they were originally designed for. And then there are voicebanks that simply aren't flexible enough for the job.

Official English voicebanks makes those tasks a lot simpler, but they're not immune to tweak sessions.

In fact, no Vocaloid tune that are notable haven't underwent a massive tweaking session.
