The "advertisers" come up with a new option, how to deliver their "product" to the user. So it's sometimes inevitably to catch some ads on websites. But usually it's quite easy to watch youtube without annoying ads.
@grgnd thank you for the support. Adguard filter support would indeed not only improve the built-in adblocker, but also make more people migrate from adblocking extensions. A win-win for Opera and the users imo.
