I mean, sure, you can blame this batch on the internet and necessary SEO, but good artists being skipped over is nothing new. There were days before the internet (and even after it’s implementation, but before the ecosystem you are talking about existed) where artists and band with immense talent were lost to time because things didn’t line up just right for them to be successful. Bands played gig after gig, sending their singles to record companies and nothing happened. Just being good at a thing has never been enough. That’s just step 1. Often, the right person has to see you, and that person has to be in the position to elevate you at the time. Maybe that industry guy was just in a bad mood that day and wasn’t enjoying any music and you just got a bad night.
And we have examples of visual artists dying in obscurity only for their art to hit it big after their death. It’s a whole trope in the art world. Van Gogh is probably the most famous. He died penniless having only sold a single painting while alive, and that was to his brother, a frickin art dealer! He even had a guy on the inside and couldn’t make it. Impressionism was a new school, but not exactly empty. As a genre it basically got it’s own museum in the Musée d’Orsay, and still, one of the greatest artists in the genre (and probably all art) couldn’t get a fucking break. Talent is often not enough. Luck and timing have always been more important.
If they make a bad product do you want more of it, even for free?
Like, reviewers get to the point where companies send them free product for review from a long period of legitimate reviews that get them a large enough audience. It’s unlikely they’re getting their main profits from free products sent.
Obviously you shouldn’t take a single person’s review as gospel anyway, but just them getting a review copy of a thing isn’t a sole reason to discredit their opinion.
