4. A quick review from our last talk
From A New Product Mindset of Decentralization
“Internet Mindset”:
• Free (…and we make money elsewhere, e.g. sell your data to ads)
• User base is everything (…so we can sell you for more $$)
• Growth, growth, growth (…so we can sell you sooner)
• Collect as many as possible users data (…so we can sell you better)
• “All your base(data) is now long to us”. (…so my profit is none of your
business)
• Platform “lock-in” (…so you can’t go away even we screw you up)
