Remember, Chrome is not installed by default on Windows PCs; Edge is. People are using Chrome because they want to. They could just as easily download Firefox and uBO, like more-savvy users do. Unfortunately, too many can't be bothered. Should they be saved from excessive and intrusive ads? Again, they can easily install uBOL on their Chrome instance, or they can download and install FF+uBO. Or use something else like Brave.
>Tell your friends to use Firefox, people.
Absolutely, yes. Just don't be too surprised when you visit them later and they're still using Chrome (or Edge) with no ad-blocker at all. You can lead a horse to water, but you can't make it drink.
