Taylor Swift's challenge to Apple to pay acts on its streaming service has seen her accused of hypocrisy after details emerged of her attempts to control photographers covering her concerts.
The Shake It Off singer (25) said she would hold back her latest album 1989 from Apple Music in protest at the technology giant's "shocking and disappointing" decision not to pay for songs streamed during a three-month trial period.
But it also prompted a less complimentary reply from photographer Jason Sheldon, who posted what he said was a copy of her photo policy which gives her "free and unlimited use of our work, worldwide, in perpetuity".
He said: "How are you any different to Apple? If you don't like being exploited, that's great ... make a huge statement about it, and you'll have my support. But how about making sure you're not guilty of the very same tactic before you have a pop at someone else?
"Photographers need to earn a living as well."
Ms Swift's stand against Apple came after she withdrew her entire catalogue from popular streaming service Spotify in November.
She said she was making a stand not for herself but for new artists and bands, young songwriters and producers who would not be paid for a quarter of a year of plays.
Apple's U-turn w as given a cautious welcome by music industry figures.
Alison Wenham, from the Worldwide Independent Network which represents the independent music industry, said: "The decision from Apple to pay royalties to rights owners during the proposed three-month trial period is clearly a positive and encouraging step and we welcome the beginning of a fair and equitable relationship between Apple Music and the global independent music sector."
Musicians' Union assistant general secretary Horace Trubridge said it was "unclear" exactly what Apple was proposing.
He said: "When they say they will pay, are they paying the publishers and records labels so they can pay the artists, or are they paying the artists direct?
"Also, it's one thing if you are an act like Taylor Swift and have that market share and commercial power, but if you're an act with a major label from the 1970s or 1980s, which is where a lot of the streamed music is from, you've probably got a crap contract that does not pay out much for streaming."
