This was sloppy reporting/writing. The "revenue to nosedive by $17 million to $22 million" was the specific effect only attributable to their Covid-19 financial assistance program. Here's the quote directly from Uber's release:
"To support those whose earning opportunities have been depressed as a result of COVID-19, as well as communities hit hard by the virus, we announced and implemented several initiatives during the first quarter of 2020, including a financial assistance program for drivers and delivery people. We intend to account for this program as Contra Revenue, which we expect will reduce GAAP Revenue by an estimated $17 to $22 million in Q1 and an estimated $60 to $80 million in Q2."
