The unfortunate part about this is that you're still rendering the ads. Whereas a big point of the usage of adblockers is to save network transfer or computer power or make your browser faster, this proxy browser solution only solves the issue of "I don't want to see things I don't want to see".

It's fine for the people who aren't on metered connections or have ever more powerful computers to keep up with the pace of the web - but in some respects, the ad people have won in making it terribly inconvenient.
