Yeah, I can tell why this is from adhddd.com, it’s all about assertiveness. People with ADHD in general (including myself, to an extent) have trouble with being assertive, so most of the phrases in this chart try to change a meek or mild-mannered response to a more assertive one. I think part of the struggle of life is finding balance because while some of these are generally improvements, others are generally worse, and the difference will depend on the tone you’re going for and the person that you’re sending the email.
