Oh this is about the "Database Rights".<p>In essence, EU, UK and the USA has different opinion on the ownership status and rights of databases.<p>EU: Databases are similar to other copyrightable works, thus you can't simply copy someones database.<p>UK: Like EU but with different flavour.<p>USA: There's no such things as database rights.<p>Apparently, although the positions of UK and EU are similar, since UK is no longer in the EU and there's no mutual agreement on how to make things work those who want to have their databases protected by the law need to move to the jurisdiction that fits their needs and in the case of OpenStreetMap that would be EU.<p>fun fact: The last time the database rights was a hot topic, it was about Google copying the database of a small company that specialises in building a database of net worth of celebrities.<p><a href="https://news.ycombinator.com/item?id=24105465" rel="nofollow">https://news.ycombinator.com/item?id=24105465</a>
