I don't run one because I choose to support the free content I receive (be it articles, videos, or similar). Without ads either they would have to charge, the quality would go down, or the content simply would stop existing.

That being said, I understand why others do. Adverts remain a source of privacy violations, legitimate security issues, and slow down a lot of websites.

I do run Flash click-to-play, and have EFF's HTTPS Everywhere installed. Those both negatively impact ads, but it is inadvertent and unavoidable. Both are set to improve security, if ads require an insecure connection or flash then more fool them.
