So assuming it's the same Max Johnson I checked Bandcamp
https://maxjohnson.bandcamp.com/
and found that he has 13 releases since 2012 which isn't a bad release schedule and because of the sales platform he should be getting a reasonable slice of each purchase, I'm really not sure how it squares with the statement
" the streaming companies have ostensibly wrestled almost all the income from recorded music away from the artists, because it only discourages people to make records".
