The discussion about the "input" has been had often enough, but I'm also concerned about the "output" part by now. If they find that the Linux support does not fit their strategy for some reason, they could choose to "retire" the feature tomorrow and remotely remove it from all Chromebooks. If they find software X to conflict with their business interests or obligations, they can just ban it.

As a user without control over your device, there is nothing you can do about it.
