Their sales dropped, none of what you say makes any sense. People didn't just suddenly stop shaving after their adverts, it has been a gradual decline. So if that is the reason, why did their sales take such a sudden nose dive during this downward trend? Perhaps it was a certain advertising campaign?
You aren't making any sense at all, and you can see the desperation in your post by the fact you have to try and get personal about it. Mind you, I would be clutching at straws if I had come out and tried to make out that their sales had risen.
No you're the one desperate and clutching at straws.
Here, written before the ad released, a piece on the pressures facing Gillette:
The absurd quest to make the "best" razor
Notice it says Gillette had 57% market share in 2018. Notice also it mentions challenger brands like Dollar Shave eating into it's market and changing consumer habits around beards and general attitudes to being clean shaven affecting the entire industry.
So what was the impact on the market share? Let's look at a P&G's financial statement 2019, the one you're getting so worked up about being $8bn down:
https://www.annualreports.com/HostedData/AnnualReports/PDF/NYSE_PG_2019.pdf
" Grooming: We compete in shave care and appliances. In shave care, we are the global market leader in the blades and razors market. Our global blades and razors market share is over 60%, primarily behind the Gillette franchise, including our Fusion, Mach3, Prestobarba and Venus brands. "
So virtually no impact on market share then.
As with the left wing variety, right wing cancel culture and virtue signalling is mostly the preserve of a few very online, very loud, people that bear no relation to the real world.
