Not sure you're correct that these employees have Spotify's best interest in mind. It's just as likely that they have their own political and social agenda which they are able to leverage by working at Spotify.
That's a really strange assertion to make. A corporation the size of Spotify giving that much leeway to individual employees on a major business relationship like this is basically unheard of and fairly implausible, and these sorts of things have been going on in a calculated, intentional manner for over a century in various forms of publishing.
