Ive reneged on full time offers. There are no blacklists as long as you do it respectfully and as early as possible. I still get recruiting emails from them. It’s an employees market right now so this happens, especially at a large company nobody will know or care

This, plus a few other comments from the thread. Candidates get better offer and renege all the time; it sucks but that’s business, most hiring managers will suck it up. You’re young, you have your entire career in front of you, now’s the best time to experiment and to figure out what motivates you. From the sound of it, you’re not likely to find it in the first internship (you never know... but dragging your feet into a job is not the best way to start). Plus: it’s an internship; unless the company is a very early start-up running on interns and happy pills they’ll be fine without you. The only thing that would give me pause in your situation is whether it could have a negative impact on the friend that referred you.
