>"Wow the Sex Pistols a corporate created punk band aka the Nsync of punk."
What an incredibly uninformed thing to say. I guess you don't know that it was their legendary gig in Manchester in 1976 that actually kicked off the whole "Punk" movement? See:

Also Paul Cook and Steven Jones had a band called the Strand years before they met Malcolm McLaren. And it was Bernie Rhodes(the Clash's manager) that got Johnny Lydon to join the Pistols. Malcom McLaren ran an independent clothing store that sold t-shirts and bondage inspired clothing. How is any of that even remotely corporate? Or even remotely comparable to a boy band?
>"I have no idea why anyone even cares about this band band .."
There are so many great bands that formed because they were inspired by the Sex Pistols - The Clash, Buzzcocks, The Smiths, The Fall, The Pretenders, Magazine, X-Ray Spex, Joy Division, Siouxsie and the Banshees [1][2]. In fact probably most of the great post-punk that came out of England between the late 70s and early 80s.
Their whole ethos was "anybody could do it." You can not get any more DIY and any less corporate than that. They were actually a reaction to the corporate state of music at the time.
You might want to read up on your rock history a bit.
