Well, here's the language in the license that apparently is too hard for you to find:
4.3 Notice for using output (Contents). Creating and Using a Produced Work does not require the notice in Section 4.2. However, if you Publicly Use a Produced Work, You must include a notice associated with the Produced Work reasonably calculated to make any Person that uses, views, accesses, interacts with, or is otherwise exposed to the Produced Work aware that Content was obtained from the Database, Derivative Database, or the Database as part of a Collective Database, and that it is available under this License.
I can't read it for you, but I can summarize it for you. You are required to make sure that someone who uses the product (i.e., Clickhouse's marketing stunt thingy) becomes aware of the license and origin of the underlying data. And not by digging into some GitHub repo, but right there, on the page.
Not at all. It is the polite request to please correctly attribute the data that a company is using for their marketing stunts.
I love the fact that techbros being called out for violating other people's intellectual property immediately revert to "TROLL!" or "this is too hard!" instead of actually engaging with the question at hand. And btw - until you actually create the software stack to collect the data and run an aggregator, don't condescend on people who do the hard work that you seem to feel free to copy in violation of said license.
please read the license and its requirements.
It is YOUR responsibility to comply with those requirements in order to be allowed to use the data.
It is ridiculous that a well funded company asks a volunteer community to tell them how to comply with the license - after they have violated the license and used it for a marketing stunt.
I find it super frustrating to see well funded tech companies boldly abuse open data resources and assume they can just get away with it. I guess that's the theme of 2024.
But to make it clear: you are in violation of the license the data is provided under, and as one of the copyright holders I object to that.
