I don't find any disturbing, nasty (!!) and dirty (!!) things. He just said what he thinks. He thinks that you might have done a better job and that the activity level stayed the same. You might not agree on what he said, but you must respect what he said and can't call that speech a "nasty and dirty speech".
Now, I'd like to say a few things on the topic. I must admit that Griffin has a big political talent. He was able to convince even members of my party and centre-right people that I thought close to me to vote for him. I know he promised to be a non-partisan president and to focus on revitalization of the game and to NOT run for re-election in case of success on this intent, but considered that he's running for a second term, I am inclined to think that he's not been succesfull. Some of these people (I know it's insane, but some gave me a 1st preference in the Senate election while not voting for me in the presidential election) are now silent, other people (some even passionately campaigned for him) are now repented, but this is another topic.
Back on the main topic, I think things are better than October, but it's pretty normal. In October, Atlasia was in a very bad shape and doing worse than that is really hard. Also my impression is that this "change" was determined more by the work of the ConCon and by an active Senate. Important parts of the federal government have not worked well. The Vice President was litterally transparent. He just opened some confirmation hearings, voted to break a tie (after my PMs), but he wasn't never involved in Senate works. Personally, I think the VP shall be the "bridge" between the federal government and the Senate.
