The article just talks about foreigners enlisting to assist Ukrainian military, and it lists a few personal stories of those. The only potential reference to Sam Hyde is this sentence: "Hyde, a 28-year-old from the U.S. Midwest, said he was already in Kyiv and expected to start military training on Tuesday." This is a wild stretch to use this as an example of Reuters being hoaxed in this article. For all we know, it could have been a different person with the last name Hyde, it isn't exactly uncommon. There are no references in the article to the details that could definitely identify it with the Sam Hyde hoax that we saw on Twitter.
