and the company has driven innovation for decades
Uh... geez. Where to even start?
The first and last real MS innovation was the Microsoft BASIC interpreter which became ubiquitous in 1980s home computers. Everything else they ever did was shamelessly stolen and/or bought and/or badly copied from others. Even MS-DOS started out as a bought-out CP/M imitation.
They disparaged GUIs and the whole idea of user-friendly computing until the Mac proved them wrong. It took them a decade to come up with a usable competitor (Windows 95). Then it took them years to recognize the importance of the Internet, so they killed the competition by illegally leveraging their monopoly on Windows desktops. With the competition dead, they stalled IE development and set back web innovation by a decade until Firefox broke the market back open.
Now you can see them screw up the same way with mobile devices. It took even Bill Gates until last week to admit that the PC-centric model may be "changing". Thankfully, with Gates gone and that dancing sweatmonkey in charge, they don't seem to be capable of their past level of predation anymore.
MS has always been a follower at best. It has frequently been a predatory abuser of its monopoly. It has usually parasitized on the innovations of others. Embrace, extend, extinguish was always how they operated. It has never been an innovation leader.
