I think this conflates "ecosystem" with "closed ecosystem" or "walled garden."

I agree that closed ecosystems are frustrating lock-in tactics. But open ecosystems exist - KDE connect actually shows a good example. It was built for the KDE ecosystem (desktop environment, apps, and services that integrate and work well with each other), but makes the protocol open, so clients can exist for Gnome, and other platforms.

I recognize this is mostly semantics, but wanted to call it out because I think the integration and interoperability afforded by an "ecosystem" is extremely user friendly in general. It only becomes a problem when it is weaponized to lock you in.
