Read the following paragraph and extract the answer for the question: What is the full name of the person that is very critical of modern mainstream pop punk bands?  With their love of the Beach Boys and late 1960s bubblegum pop, the Ramones paved the way to what became known as pop punk. In the late 1970s, UK bands such as Buzzcocks and the Undertones combined pop-style tunes and lyrical themes with punk's speed and chaotic edge. In the early 1980s, some of the leading bands in Southern California's hardcore punk rock scene emphasized a more melodic approach than was typical of their peers. According to music journalist Ben Myers, Bad Religion "layered their pissed off, politicized sound with the smoothest of harmonies"; Descendents "wrote almost surfy, Beach Boys-inspired songs about girls and food and being young(ish)". Epitaph Records, founded by Brett Gurewitz of Bad Religion, was the base for many future pop punk bands. Bands that fused punk with light-hearted pop melodies, such as the Queers and Screeching Weasel, began appearing around the country, in turn influencing bands like Green Day and the Offspring, who brought pop punk wide popularity and major record sales. Bands such as the Vandals and Guttermouth developed a style blending pop melodies with humorous and offensive lyrics. Eventually, the geographically large Midwest U.S. punk scene, anchored largely in places like Chicago and Minneapolis, would spawn bands like Dillinger Four who would take a catchy, hooky pop-punk approach and reinfuse it with some of punk's earlier grit and fury, creating a distinctive punk rock sound with a regional tag. This particular substrate still maintains an identity today. The mainstream pop punk of latter-day bands such as Blink-182 is criticized by many punk rock devotees; in critic Christine Di Bella's words, "It's punk taken to its most accessible point, a point where it barely reflects its lineage at all, except in the three-chord song structures."
