As someone who is supposedly a PC tech person, some of your comments suggest you aren't.
Your "fix" is not feasible
And which fix is that? There have been a few suggestions throughout this topic. Are you referring to Lawrence's post on page one, which most people finding this topic seem to treat as the only page there is to read? I would have to guess "yes" since no, clearing all website data isn't a permanent fix. That shouldn't be a surprise since that only dumps the current cache off your device. As soon as you go back to a site, or any other site that shoves ads down your throat, you'll see them again.
You can say apple has no part in this, & no way to fix it, but that's just incorrect.
I see. No one can control the vastness of the Internet, but you think Apple can. That if they blacklist an ad server, there will never be another one to replace it. Or, the blacklisted site won't simply register a new domain and continue on. I'd be very surprised if such places weren't already operating from multiple IP addresses.
How do you think all of these scam sites that pop up warnings your device has xxx viruses on it and to call a toll free number NOW stay out there? They get shut down or blacklisted daily. The crooks open replacements daily. It's a never ending game of Whack-A-Mole, but you think Apple can somehow win against ad servers.
They just refuse to release their death grip on their precious OS, even at the cost of functionality.
Um, sure. Just like Microsoft shares everything about Windows with everyone.
My next phone will most likely not be a iPhone, simply because I am a power user that demands access and control of every aspect of my devices, even at the cost of having to learn how.
I was an avid PC user since our first computer, an IBM XT clone. It took me a long time to learn that hitting myself over the head with a sledgehammer actually wasn't fun. It was for a while, if you're the type of person who likes to tinker (I do), because you sure have to learn a LOT about protecting your computer - constantly. Macs and iOS devices? Yes, I keep up on what's happening that may be a viable threat, but for the most part, I can just turn my devices on and use them without thinking about how I'm going to keep it from being attacked today.
If you want to beat yourself up on a device that requires constant vigilance; where their official app stores (Android in particular) are swamped with malware; where apps that do more behind your back than what they say they're for, then by all means, buy something else and spend more time protecting your device and data than just using it. Careful which Android phone you buy. There was a recent load of them found with malware right in the firmware of the device.
