Can companies trust Microsoft again? Intelligence agencies received information about the 0-day vulnerabilities of Windows and Skype

Not so long ago, the PRISM scandal broke out. Someone remembers the scandal in 1999 about the backdoor . After buying skype, there were a lot of discussions about the changed architecture. Say, the changes made in favor of surveillance. However, all these, sometimes not groundless, rumors pale in the background of the last scandal.
A Microsoft spokesman, Frank Shaw, confirmed the presence of an early warning program for non-closed 0day vulnerabilities in corporate products. Thus, the NSA received a tool for penetrating any user computers with Windows or Skype installed. The company's participation in these programs was voluntary by Microsoft. According to Frank Shaw, this initiative existed to assess and mitigate the risks associated with future fixes for these vulnerabilities. Considering that Skype is widely used on Linux, Mac OS, Android, iOS, the coverage is large. As the size of the next scandal associated with the company. A reasonable question arises, is it worth to trust your data to this company. Which is frankly hypocritical, paying rewards for detecting security problems, on the other hand, merges the data before the security services close holes in their products. And shoots videos a la scroogled.
