Seems far-fetched that normal webpages would use canvas as the primary method to render text something like Google docs makes sense because it's a complex application and consistency is important. For these type of sites if they choose to put ads on I would not try to block them because clearly the effort the developers put to build them justifies displaying ads. Additionally, I can see future ad blockers also getting more sophisticated by finding a way to block already rendered elements on a canvas without having access to the representational elements (reverse engineering).
