Apart from a few geeks using firefox on android, mobile browsers generally dont hinder ads
Every single browser except Chrome would be a better way to put it.
You can install an ad filter, set up content filtering, and then use Safari without seeing ads.
AdGuard on iOS blocks ads just fine. I pay $5 a year because then it blocks YouTube ads.
Brave browser.
Samsung Browser and Safari both very much enable ad blocking, and especially Samsung actively notifies users to enable it.
There have been lots of complaints about a well-funded advertising campaign from Hobby Lobby called "He Gets Us". App users are getting DMs from the advertiser and are unable to block the adverts or user. Other advertisers are blockable, which stops those ads.
And access to push notifications
iOS 17 supports pwa notifications, so it's pretty much exclusively ads at this point
iOS 17 isn’t out yet.
"support" means that user needs to explicitly do something (add as an "app") before you can get notifications which is not as easy as in the app
And access to more data for analytics and attributions than is available to a web page.
