I believe Jack's statement, while obviously well intended, is misleading. Twitter will stop accepting money for political advertising. This is not the same as "stop(ping) all political advertising on Twitter". Other people will continue promote things there and get paid for it regardless of what twitter's policy is. I worry that a widespread misunderstanding of this will increase the public's vulnerability to paid manipulation on Twitter, particularly in a way that maximizes the impact of the least honest parties.
