Feel like bob3160,
When Google Chrome does not allow extensions on Windows anymore, Vivaldi may or Sleipnir.
I am gonna worry the moment when for instance firefox browser and extensions and others get banned from various platforms
to no longer hinder big player's adware (Google, Bing, facebook, etc.).
Again then that will be very decision, if one cannot even block mal-ads any longer.
Let us wait how far they will go taking the browser further out of the user's hands.
