I generally agree with the sentiment—if something is free, there’s often a tradeoff. But when there’s a paid tier, the free version can act more like an entry point or hook to get users into the ecosystem, rather than relying on harvesting user data. In JetBrains’ case, broad adoption brings a lot of strategic value on its own (like establishing industry standards or building community mindshare), so it makes sense for them to offer a genuinely free version without necessarily treating users as the product.

Exactly, this I why I won't use Linux or Firefox, I don't want to be the product.
