I personally see ClickHouse still improving in terms of overall usability and becoming much more polished, introducing features like full-text indexing, JSON data type, etc, all open-source and completely free. The commercial offering deviates from the "bare-bones", "build-it-yourself" storage, but, again, in my opinion it makes perfect sense to commercialise this part of it, to allow the product overall to continue to evolve and be successful. Otherwise ClickHouse as an open-source database probably wouldn't be able to evolve so quickly since the needs of Yandex don't always align with the needs of other users of the database
