comment Tick data collection
Here's some useful links from google: trade-ideas.com/Glossary/Tick_Data.html investopedia.com/terms/t/tick.asp#axzz1xdsUTCJQ . Your other problem can be solved by just taking a little time to think out a solution. Maybe write a simple function in the language of your choice to match everything up based on the timestamps.

comment Why isn't all market data free?
I am by no means an expert and still a student myself so take my opinion with a grain of salt, but I'd imagine that the big hedge fund guys and bankers aren't thinking in terms of what would be good for the market. Their only objective is to preform which reduces your question/comparison to a matter of integrity and morality which is an entirely different debate in my opinion.

I think a better question is why offer something for free if someone is willing to pay for it? You may be underestimating the power of financial incentive
