The only issue i find with your proposition is that one could simply rebuild a whole site on a different platform: while that is true, one does not own or hold the code for the site as built using a website builder afaik (correct me if im wrong) and hence it is difficult to get similar results as the one on the "current" builder and takes up extra labour, where hiring a website builder and maintainer will ensure the ownership of the code.
Google will decide what people should and shouldnt do. Google will decide whether people deserve privacy in their lives for certain things or not. Language of the abusers.
I dont know of any good reason to have gratitude for a corporation for anything. Having gratitude of the workers and academics that made it happen on the other hand? Sure, that's fair.
