I think there are multiple reasons for that.

The first is an increased fatigue caused by some poor quality posts OR posts presenting the same thing again and again just by opportunism (e.g. boilerplates where people just share their thing as an Ad). Therefore, the trust has decreased and people start asking themselves "what's hidden behind".

Another reason might be related to the surge of cyberattacks of all kinds. Lots of comments here are not super nice, but they are polite and ask good and legitimate questions, especially regarding cybersecurity.

As long as people are polite, argumented criticism should be appreciated.
