Interesting news indeed! I very much wonder what it means long term in terms of Licenses. I would imagine much better future if Clickhouse would become Foundation driven process which gives good protection from license change (through I'm biased here) - Currently Clickhouse fully under Apache 2.0 license may look too good to be true compared to where many successful VC funded projects took licenses of their projects (think Elastc, MongoDB, Redis)
In any case though I expect a lot of growth in Clickhouse community now and investment both engineering and most importantly Marketing - I think Clickhouse technology has a lot more adoption potential than it currently has
