Like most things in life, there are multiple sides to this and multiple sides that are "right" at the same time. There are also lots of excuses being thrown around which are weak at best. At the end of the day, the higher the share price the better. 

1. Could they have bought rather than sold? Sure

2. Did they potentially kill the rally? Sure

3. Could they advertise and get a functional IR? Yes

4. Do the employees and executives deserve a (hopefully fair) payment for their services? Yes

On the other side:

1. Was the amount of shares they sold small? Sure

There are only a couple sides that are wrong:

1. The parties including Mika's (alleged) comments about the share price being of no concern and incidental to the tech. 

2. People who marry stocks/companies and can not accept healthy criticism. 

3. People singling out others for some group bulling for their equally valuable (or not) opinions.
