Yes! There is no desire or intention to charge for the use of LCBO API. I don't own the data, and neither do you.
The LCBO's website is crawled in the early hours of the morning to get up-to-date information. Search engines like Google use this same technique to index web pages.
I want to see what developers create with access to this data. I feel that publicly available information should be free and accessible in as many ways as possible.
Yep, do your homework before you gonna hate.
Some parts are, but the meat of the project is still closed source. The intention is that everything from the crawler to the web frontend will be open source in the future.
