green day dookie was the first CD I owned. It was the first thing I found on the street (read: garbage), and inspired my interest in free and used things. I owe them a lot. But man do they suck.
I don't know, I've always been more of an Offspring fan, but I don't think it's fair to say that Green Day "suck". They've obviously achieved an impressive level of success and people still pay attention and listen to their new releases decades after they were truly relevant.
I never was a big fan of Dookie but their next album, Insomniac, is still an immensely enjoyable album to this day. Whether it's technically not 'punk' and is instead 'pop-punk' or just 'rock' makes no difference to me. The fact that their music isn't overtly anti-establishment doesn't affect the quality of the music.
In fact, and this may get me into trouble here, I like the Dead Kennedy's 'Plastic Surgery Disasters' just as much as I like Green Day's 'Insomniac'. Is one punk and one not? Who cares? I quite dislike the purity tests in some genres of music (like punk and metal). That's something I've always appreciated about pop music - it doesn't have to adhere to some nebulous framework to qualify for the genre, it simply has to be popular (e.g. Beatles were pop, Madonna was pop, and Arianna Grande is pop - very different styles of music)
You like the music you like and that itself is as punk rock as you can get.
The difference between "Lookout! Green Day" and "Warner Green Day" is one of DIY vs Payola. These days, it's much easier and potentially more profitable to go the DIY route, but back then, you needed a sugar daddy to "make it big" fast. Taking the easy route meant Green Day were shunned by their original fan base (somewhat justifiably so,) but they had more energy, raw talent, and Buzzcocks hooks than anything else on top 40 radio with the exception of Nirvana (which is why Warner was trolling for talent in the first place.)
It's hard to call any "punk" bands sellouts after Nevermind. Were Hüsker Dü sellouts? They signed to Warner in '85 (almost a decade before Green Day.)
The music business is harsh. If you're in a band and into it for the long haul, own your masters and go the DIY route. Your fans will find you and are more likely to pay directly when they do. If you're in a band and want to make it big fast, consider this often cited article from Steve "Mr. Gold Bracelet" Albini on cashflow:
I ignored Green Day when I first got into punk because they seemed like radio-rock music. But years later, when I was in grad school and stopped caring so much about how I classified bands, I was blown away by "American Idiot." That album was brilliant.
I listened to Offspring's album "Smash" a bunch in middle school, which made for an interesting revelation when I devoured Bad Religion's entire catalogue in high school.
