GSK knew that their drug was worse than useless, they knew that children would die as a result, but they deliberately withheld damning data and misled clinicians. For this (and many, many other acts of deceit) they were fined a total of $3bn by the Department of Justice.
The paper has never been retracted and paroxetine is still widely prescribed to adolescents.
"Sounds like they need more anti-depressants"
Just blaming someone else, like marketing and sales, is quite often juat a lazy excuse to not have to look at oneself. Goes zhe other way round, so. Marketing saying "we didn't force them to find value X" might be literally true as marketing almost certainly didn't use these words. But pressure cam be applied in more than one way, it doesn't have to be explicit.
One good example is the series Chernobyl. Pressure from above to deliver certain things, ignoring truth until it's too late and then looking for someone to blame. Plant management did it with the reactor control crew and the political higher ups indirectly with plant management. So yes, all of them have to blamed. Not simply a communist problem as this thread about pharma R and D shows, right?
Whether for reasons of communist 5-year plans, capitalist pharmaceutical industries or even just the personal desires of an academic to prove a pet theory, publish or whatnot.. incentives and pressure to cheat exist. That's one reason why replication is so important.
Selective publishing and "p-hacking" though, these are research/academia pathologies not marketing ones.
