What happens when the company changes direction? If there's a shift of priorities, an internal restructuring, a "strategic startup pivot", an acquisition?
Not to assume bad faith on Kaggle's part, but we got burned one too many times with private companies pushing their proprietary ("open") platforms for gobbling up data. The "it's free! just create an account — data lock-in — gap after project death/monetization" pattern leaves me a little cynical.
It's awesome that resources like these exist, but I'd be more comfortable paying attention if this was hosted as raw data somewhere (Github?), with a clear licensing and access model.
