Nice to see more empirical backing of the Bullshit Jobs theory 
The research found that people working in finance, sales and managerial roles are much more likely than others on average to think their jobs are useless or unhelpful to others.
The study, by Simon Walo, of Zurich University, Switzerland, is the first to give quantitative support to a theory put forward by the American anthropologist David Graeber in 2018 that many jobs were "bullshit"—socially useless and meaningless.
"socially useless and meaningless" is the phrasing they used
The average ad tech engineer at Google or Meta probably provides a couple dozen millions of revenue to the company but socially, it's useless and meaningless
do you think it is really meaningless? seems to me there is hella meaning

Considering google and meta are advertising companies, the meaning is a net negative.
