How has Twitter's ad revenue gone? They made the policy to eschew political advertising, so they could serve as a (somewhat imperfect) control group. On the other hand, they also haven't had a high-profile advertiser pull-out like Facebook did either.

On the ubiquitous political ads, I had to fax something to my doctor last month. I didn't want to subscribe to something to send a single fax and all the fax services that I might have used were unavailable thanks to the lockdown. I found a service that offered free faxing with an ad on the cover sheet. I didn't think twice about it and sent the ad. The confirmation page also had an ad on it. For Trump/Pence. Now I'm terrified that the same ad was on the fax and I'm going to need to get a new doctor.
