I agree with your sentiment but you cannot deny that Tony's frustration with the platform is evident in the tone of his response. Those who have had issues are easily frustrated by those who come across as apologists, offer up a revisionist view of history, or provide alternate facts on platform stability.
Robin is clearly wrong in my opinion however in his view that Alex fulfilled his promise to the community; he did not. We had a December update that took some systems down for weeks, and one that is causing ongoing issues with device communications. We had a 2 week long database problem that was never acknowledged on the status page which was causing random failures of Routines, SmartApp, and CoRE. Routines are still bonked right now.
If you want to use alternate facts, then yes, Alex fulfilled his promise and delivered stability. From my wheelhouse, we have a lot of rough seas ahead.
