Like I mentioned in the post, there is no way to programmatically upload anything to the Shopify CDN and the CDN cache cannot be invalidated once you upload a file. If you want to update an existing resource, all you can do really is upload a new one.
This ofcourse still does not completely prevent people from abusing it, but it does restrict usage to a large extent. There is also the issue of giving out a cdn.shopify.com link to your customers instead of something that has you company branding on it. This is not a problem for us because our customers do not have to manually add this snippet to their website and we do it via an API instead, so this link is not apparent to our customers
