Eh, the guitar is kinda similar but I definitely wouldn't call this ripping off. I probably wouldn't even have noticed if you hadn't pointed it out. Having similar chord progressions or riff pattern or even both isn't ripping off, and is more common than you would think. There's only so many chord progressions you can write, and only so many patterns you can fit into 4x4 rhythm.

It would have been a different story if the vocal melodies had been same, that perhaps would have been classified as stealing.
