Google is never against advertisement. It is against SERP manipulation by way of buying/selling links concerning high PR sites.
If one has followed the penalization issue throughly, he/she should know that - advertisements using
no-follow tags, Java Script redirects are always allowed by Google. It only when webmasters/SEO firms buy/sell high PR links which naturally manipulates SERPs that Google is against.
I hope my answer is clear to OP.
