I can sympathize with the sentiment that scientists should just report the objective facts and not inject their own opinions into what they tell the public. Another comment suggested that this can lead to distrust like with COVID-19.

That said, I think science communication is an art form which takes skill and practice. If you are a scientist doing research on aspartame in mice or whatever, then what the media and laypeople are interested in is what the results mean for their lives. At some point you have to give your informed opinion or else others will interpret the results for you, probably incorrectly.

I think that the scientists are trying their best to communicate their professional interpretations of the data, but it's difficult to do so in a way that will please everyone. Especially when some parties are actively hostile to the message you are trying to communicate, and will nitpick whatever you say using the least charitable understanding.
