But Eric, how much would you be willing to pay in subscription costs to gain all of that? NOTHING is free! I find it incredibly misleading, the 'free' sites, because someone is paying for everything, directly or indirectly. Putting data online is expensive - equipment costs, maintenance costs, building costs, IT costs, cyber security costs, bandwidth costs, development costs, etc. Some data can be acquired freely, but much other data has acquisition costs. But even if there's no acquisition cost, there are still all the other costs in making and keeping it accessible.
