Sorry, the freedom of speech defense is for when people are repressing the message itself, not the methodology. Face it, to a point, we like advertising. We come to sites like this for it. Show me the commercial for the new Marvel movie. Tell me what games are coming out and make them look cool. Hey, A&W has a new burger. A sale from GOG.com. the new humble bundle. We want to be marketed to.
Sadly, these ad execs have gone well past the point of common sense. They'd whistle a brand jingle in our ear 24/7 given a chance, then get surprised we try and force them to stop. It's honestly amazed me how much it probably has hurt their own goal in the long run. Who hasn't avoided clicking a banner ad for what was probably a legitimate store because it might not be? Hell, that's probably why they are so intrusive. Who actually clicks on the obvious phishing scams and follows through anymore? Probably not enough to pay the bills of all these sites, but mined data on demographics can be sold and marketed, not to mention any boost from those needing to pay to get malware and ransomware removed.
Look, we're a soft audience. Make your ads good, varied, abut good products, and keep in mind the technical limits of most computers so that whatever you do doesn't kill the machine, and we'll watch your ads almost willingly. Data mining, malware, obvious scams, those should be obvious issues you need to clean up to even be reputable, then we can talk about auto playing video at max volume, ads resizing just as you try and click another link, and how often I can see a WoW ad before I'm sick of it. And to the sites using such advertising, I get you need to pay the bills, but ask where the money comes from sometime and if you want to make it from a company advertising "make $5,345 per month at home" on your site, or trying to get people to update their browser while really installing a virus. Yes Escapist. Those have happened to me here.
