I see what you are saying, but I think the impact of a post like this on something so intangible as "market sentiment" is extremely tenuous. It's hard to measure/quantify but I'd be shocked if it's more than a rounding error.
On the other hand, there are actual fundamentals like economy-wide inflation, employment numbers, GDP growth, supply/demand curves, etc., and it's important as an operator to have information about how the economy actually is, and more importantly how it's changing. I think the benefit of a post like this is much less tenuous; it provides insight into how the broader market conditions are panning out in our specific corner of the economy.
So yes, every measurement perturbs the system under measurement. In some cases that can be substantial. But in this case I don't think it is so.
Yeah also looking at what jobs are in demand at recruiters from LinkedIn, I can see already since the pandemic it's more from companies with proven business models and rather small startups. Good to see some real numbers actually. But of course the effect is there, job seekers and companies get more cautious. Still, better than hiding this data. Also I don't think there is a real reason to worry within tech
