There's some excellent insight here. Creative work does not get the same respect as other professions, and creative artists are somehow expected to work for free in the beginning of their career for the intangible "exposure." I think there is an important distinction to be made here however. I may be wrong, but you state, "If you cannot afford to buy their art ... merely using their work and linking it can drive sales." This almost sounds like you are justifying piracy as long as someone promotes a work. It may not be what you meant since it was written a little vaguely, but I just wanted to point out that this is the wrong approach. Youtubers I believe differ a bit from this. Yes they should absolutely link to the work, especially since many of them profit off of using the work, however they are ultimately selling their own brand and commentary/parody of another work, which would fall under fair use.
Just some thoughts. Thanks for your post!
Well, I am said 100 times I am not at verbal expression. so I'll say it again. I.. am not... good at verbal expression. In fact, my lack of verbal expression got me bullied out of a Facebook group. It all depends. Now art for one thing. You can re-post on social media and link the source ( etc Deviantart Twitter) and if the artist has their store on their profile the person could buy a print. Request commissions from artist can help them. For games, most of them have a free demo to get people to buy it. You can present the demo and link the full game for people to buy. But you thought I was condoning piracy for games. Music is always free to use depending on the type. Spotify streams support the artist. So there are ways you can show support for free.
