While I can understand Twitter's move, I think a permanent suspension of the account will do a disservice in the long run, at least the way it is implemented right now.

Each and every tweet by him now simply shows "This tweet is unavailable." See the legendary covfefe tweet, for instance: https://twitter.com/realDonaldTrump/status/86976699489946828...

I would prefer if they marked his account as read-only. Maybe after the inauguration.
