True but maybe they will be applying the tactic at Azure.
Their new strategy appears to be cloud services, all in [1]. Desktop, mobile, hardware, patents, dev tools... everything ties back to encouraging Azure use now. They're offering massive partnerships and credits (first one is always free) to attract new migrations. In the last year their managed service primitives (db's, queues, lambdas, lb, etc etc) has matured tremendously, so now it's convenient and practical to quickly build full hosted applications. Like AWS but different.
As they make more open source contributions, forking popular projects and making their own spin on things, there can be MS flavored Kafka and Classic Kafka, for example.
Then once your service is hosted in Azure, with forked nonstandard services and APIs, it's inconvenient to leave: things aren't close enough to other clouds so you need to re-invest. This is the definition of lockin.
Here at $work we have swallowed the whole lure: investment, credits, partnership, migration, custom services. And that lure has big treble hooks in our gills.
