Spotify's (SPOT.N) CEO Daniel Ek renewed his attack on Apple (AAPL.O) on Wednesday in a series of tweets alleging the iPhone maker "gives itself every advantage while at the same time stifling innovation and hurting consumers". Ek tagged a number of sympathetic business leaders in his 21-tweet thread, including Musk, Microsoft president Brad Smith, and Proton founder Andy Yen. On Monday, the world's richest person Elon Musk criticized the fee Apple charges software developers - including his Twitter business - for in-app purchases, and posted a meme suggesting he was willing to "go to war" rather than pay it.
