Sheeran writes basic commercial pop music. Maybe if he tried learning some minor chords or scales and tried shifting tempos, he wouldn't get popped with so many copyright claims.
"There’s only so many notes and very few chords used in pop music. Coincidence is bound to happen if 60,000 songs are being released every day on Spotify—that’s 22 million songs a year—and there’s only 12 notes that are available."
But yeah, let's feel bad for the millionaire mediocre musician.
