One need not have a twitter account to read twitter posts. Another approach is to be a silent member. I’ve had a twitter account since 2009, made 2 tweets in all that time, both of them in 2009.
The obvious thing to do is not delete your twitter account yet. Not while Trump is still using it.
Save that kind of action for later, in case twitter needs to lose several million accounts all at once. If they go against Trump.
