Personally I think "Please keep our best interest in mind at all times." might be taken as an insult. The company is by law, supposed to act in the interest of shareholders, and while I am a bit confused with why the company has done certain things, I don't have any reasons to doubt they’re acting in our best interest. The rest of the letter sounds great, MGMT will get the point, I just don’t think that one line is needed. In my opinion.
