Although dtube is praised by most users and a very good project, you had little chance to be a relevant witness in the previous conditions and probably never considered it.
Now you have and decided to run a witness. Nothing wrong to admit it. No justification needed for such a decision.

Claiming this is still decentralized and censorship-resistant is just weird. Anyway, good luck for the future.

Don't promote yourself too much or your friends without a written permission from the boss. I wonder if there's a template for that...and who you should send the requirement to... and who decides.
