Reviewers and Let's Players use the monetizing aspect of youtube because they're using the creative commons license within the aspect of reviewing which also helps promote the material they're talking about. Gotta make money somehow and you're not claiming ownership of what you're showing, only giving an opinion.
If you still feel guilty about it, you can always take an extra moment or drop the link to the artists' patreon or donation page.
