Every MS product suffered from the 'what about Windows' problems, every decision made was inflected by Windows, and every product became subservient to needs of Windows, and how that product would benefit Windows. Far enough, it is their biggest product, but it was a business myopia that made it difficult for them to diversify. And they still struggle. That said, they have a huge mountain of cash regardless, so they're probably not about to call me up for business advice.
I do hate the subscription model. I used to have my own copy of Office and I didn't begrudge the £100 or so for a copy that I could use on a couple of years and would be current for five or so years. I'm not paying to subscribe, I don't need continuous development, it's a word processor, spreadsheet etc and already has far more features and functions that I'll ever use. It's a dramatic increase in the cost of ownership (yes, you can still buy a standalone Office for Mac, but of course they deliberately stunt it, and the licensing is one computer only where it used to be five).
I think Adobe are sowing the eventual seeds of their own demise with their subscription model. Photoshop's familiarity, for instance, was gained through wide (and often not entirely legal) usage. They've locked it down to corporates and professionals and tbh, their products while full-featured are starting to look a bit tired. Yes, a lot of workflows are tied into their tools and there's business inertia. But then again, they might want to remember that everyone used to use QuarkXpress, and Indesign was the pretender.
