> the fact that it comes in the form of a slidedeck makes it hard to do itemized critiques

The slides usually cite sources, so it's pretty easy to tell if the underlying methodology is weak. (And often it is.)

I usually enjoy reading the annual reports, my biggest criticism is just that it focuses on completely different trends each year. It will go from social to AI to messaging to privacy, etc. If something is only relevant and worth talking about for one year, then pretty much by definition it isn't a trend.
