I don't disagree about the risk of chilling effects, but the methodology of this report is so embarrassingly, deceptively bad that I don't think any conclusion can be drawn from it. They basically snapshot a comment section, then return repeatedly, and enumerate the comments that disappeared. Without any insight into who (ie the platform, the poster, or the channel/page owner) removed the comment and why, this is like performing a legal analysis of the leaves that disappeared from lawns in autumn.

It has the same quality of any research or report that suggest there to be negative effects if people do see such content.

And if in doubt, content removal should be done defensively.
