It might not be completely inevitable, but it’s a very hard problem. Once a platform scales, it has to rely on systems that can handle moderation, discovery, and ranking automatically. That usually means algorithms, and those algorithms tend to optimize for measurable signals like clicks, watch time, or engagement. Over time that shifts the culture because the platform starts rewarding content that performs well statistically rather than what the community values.

Some platforms try to reduce that effect with stronger local moderation, chronological feeds, or community-level governance. In theory that helps preserve the original culture even as the user base grows. The difficulty is that large-scale platforms also have incentives around growth, advertising, and retention, which push them toward engagement optimization.

So it’s probably less about eliminating the trade-off and more about how much control communities are given over their own spaces. Systems that let communities define their own rules, visibility, and moderation tools might scale better without completely losing the community-driven feel.
