How can outline be even legal? They basically steal the content of a website and create a new page on their own with it. It just happened that the content is stripped of ads for readability, but still.
Of course I can get the content of these sites by disabling JavaScript or otherwise trivially (for me at least) edit the DOM. Obscurity isn't security, so Outline is really just scripting and caching content I could otherwise access so in the grand scheme of things I don't find the website itself to be particularly problematic in the same way I don't find the cassette tape to be. If anything my own behavior and usage of it is the real problem.
