They’ve learned forgotten more lessons than they’ll ever remember.

In the last 10 years we still see these behaviours by way of:

• changing over to a subscription model for office then dropping support for older versions to basically force people to move to their new model, locking many prior VLSC or on-premises exchange features behind very high subscriptions
• after releasing the new version of the edge browser are now using their integration in their software suite to disregard the user’s default browser choice and open in edge anyway. Having to now go through an extra menu set to tell their software to respect the default browser set in the OS
• lying about Win 10 being the final version of windows only to turn around and add a TPM requirement which automatically disqualifies a significant amount of hardware from being able to upgrade

This is just three examples off the top of my head, respectively. We could talk about ads in a paid OS, constant nags to please pretty please use their browser, breaking prior software to integrate “new” versions that don’t add any user improvements but do add significant upgrades to telemetry and usage data, and so on.
