Spying and commercialization have ruined the internet for me. Seems I can't visit any site (except some specialty sites like AA) without being bombarded by advertisements. The spying I don't care about that much because I have nothing to hide.
The ads really have changed things, they are everywhere. Especially obnoxious are the ones with video and audio that are super loud and take over your screen. I don't have anything to hide either but I don't like being spied on. The nature of the internet is changing for sure.
