The Facebook fanboy who wrote this piece is unsually naive about how business works. The Cambridge Analytica scandal broke in March and so as contracts are signed months ahead it would not impact the Q1 figures to any great extent.
For example several major advertisers including Proctor and Gamble and Unilever announced last year they were abandoning web advertising as it is just not effective. But their pullout will not impact internet platforms ad revenue until later this year. It’s called forward planning and it is how businesses ensure their operations run smothly.
That said, Facebook’s claimed success does seen a little suspicious in view of all I have read in business news since last summer. but it wouldn’t be the first time Facebook have lied about results to catch the headlines, then quietly issued amended figures a couple of months later. So we really need to wait until Q3 to assess if any damage has been done.
