Honestly I kind of get his point.
I fooled around with some basic beat making software back in the day and was having a lot of fun, so I stepped up to entry level producing software and HOLY SHIT there was a learning cliff I had to climb. It sucked all the fun out of it and I got bored really fast.
People do still want to create and make music not learn how to use a piece of software.
Honestly, the only thing marketplace sucks for is cars.
Ive only ever had luck selling cars on platforms that require you to pay to list. Marketplace just gets you an endless string of time wasters and people who want it for half the asking price.
