Viewing an ad is not “giving back” in any meaningful sense. Modern adtech primarily benefits the infrastructure providers, rather than providing a service to its “clients” or a revenue stream to site owners.

Adblocking is the only meaningful objection that the consuming public can raise to the inefficient and wasteful adtech situation. Depending on how you feel about your obligations with regards to civil society, you might view it as a moral imperative.

Your other option is not consuming ad-supported content. There's no natural entitlement you should be able to view all content in a form that suits you.

What you declare to be meaningful isn't really the issue. It's how the thing you're getting chooses to pay for itself.
