I've always wondered what percentage of "users" are "lurks" who never login, occasionally check a profile or click on a tweet on another website.

One of the previous uses of twitter was "announcements". Government, corporate, emergency, community, software, etc.

The previous move to require logging in was already a massive blow to that, requiring a payment would decimate it was a use-case.

I don't see company's/governments putting announcements on a paid platform. You can't expect people to pay for twitter for announcements.
