What we really need is for people to ditch piracy and streaming services and start paying for music again, then producers can thrive and create without the need for added restrictions.
Well, yes, that is the crux of the matter. Streaming and Youtube make zero money for the artists whilst the ad revenue generated by these platforms equals huge profits for them. So, some artists like Blank & Jones rightly block the publishing of their tracks as it means giving away their work for free. Problem is that people think they are entitled to free music. In another thread here there is criticism of Blank and Jones for their stance on copyright but none of those critics want to go to Beatport and buy their tracks. Totally ridiculous, asking someone to give away their hard work for free.
One of those critics runs a popular YT channel where he posts tracks and then asks for donations from viewers so he could buy more records. Again, ridiculous as the artists make no money from his channel but he thinks he can just take other people's work and make money himself.
These kinds of selfish and self centred attitudes, along with illegal file sharing, are what's been choking the dance music scene in the digital age. These and other issues are what the artists on Facebook are campaigning to change.
If, for example, DJs had to publish their sets every time they played and then had to pay 10% of their booking fee to the artists whose tracks they used then that would make a huge difference to those artists. With some reward for their work they would feel motivated to continue to make better music as opposed to quitting producing, which is what a lot of them do after only a couple of years in the business.
If DJs started to play only their own tracks to get around any such rules then their sets would suffer, they might miss out on bookings, etc.
Also, instead of posting tracks on YT, streaming platforms and even the major download sites many artists are choosing to publish themselves on Bandcamp, where most of the revenue goes to them. So, change is happening slowly. The current situation with COVID and the closure of clubs and festivals will hopefully accelerate the change in the positive direction.
