It is self-centred to expect everyone to work for you for free. That is why we now have AI destroying creative industries, because it has become normalised not to pay people for using their content.
In parts of Africa the local textile and clothing industries have been destroyed by large amounts of free clothing being offloaded onto them by the developed world. This has been done with good intent, but it means that Africans have been put out of work, and so that they cannot sell their clothes on the international market. If those areas could develop a clothing industry it would bring much needed money into their economy and make them less dependent on onerous bank loans.
"were you under the impression that creatives were well paid before the internet?"
Yes, they were being better paid. Musicians had unions for one. Spotify and YouTube do not pay fair rates for their music, yet rake in from advertising. Old radio stations paid better.
This has been a problem in bars and venues. They tell lies like 'it will look good on your CV/resumé" or "it will get you attention". But if many of them are willing do it unpaid, it means a lot of the pubs won't pay anyone to play.
