They have regularly bought out companies in that space (last one was Ray Ozzie's Talko, in December, and they specifically said "Talko was acquired to help fuel future innovation in Skype and Skype for Business. As part of the Skype team, we’ll leverage Talko’s technology and the many things we’ve learned during its design and development.").

Let's hope they actually benefit from those.
