Dear small online ad businesses,
Forward your thanks to the intrusive ad networks, spammers and other cretin who've been treating users badly for the last few decades, attracting hostile attention to the advertising practices.
People woke up to the fact that they are in control of the content coming through their wires thanks to the versatility of the contemporary computers. There is no return.
You should embrace current realities of the market you so love to invoke for every other subject and start innovating and distrupting. Failing that, stick with the proven ad channels such as iDevices, other locked down devices, social stalking services, local tv and radio channels and papers.
You won't be missed.
Sincerely, Internet users
