The most negative ones would be: - Content blocking: you limit access to your news to a very precise subset of people, so implicitly easily targeting and closing users's views. - Heaviness: you limit access to your news to mainly desktop targets, as most mobile networks have very limited bandwidth usage.

Also it have a positive impact on you, also me (as I decided to add it and all its subdomains to my blocklist) but a lot of users will keep living under those website's constraints, but also gaining the habit of that, thus starting to think about it as "normal" where it's really the Web and net neutrality cancer.
