I like Cisco - feels good when I type commands into the CLI.
I have faith in my fingers
Having too strong an opinion is bad for your internal chill zone, do not be mean to cisco man, not on this list !

This message originates from outside of your organisation.
Copied from smart people :
Welcome to the world of coopetition. Microsoft has SQL Server running on Linux. They also sell Windows Server licenses. Some customers want one or the other, so they give them what they want. Other customers want a solution, and they can get it.
I think enough customers (not all of them, but an increasing number) have said that open is where it's at. Cisco has been preparing but holding to its proprietary line to capture as much revenue as possible before they are forced to change. At the same time, they have to turn around the ship and change their products.
Its not easy changing a big, fat company after 20 years of doing the same thing over and over while making huge profits for little effort.
Thats the problem they are engaging with. Nearly everyone is doing better, faster, easier, more reliable networking that Cisco. Most often, at a cheaper price too. Its taking time for customers to make the switch but its a slow and steady migration.
Cisco knows this at least. And the moves to subscription licenses are an attempt to extract more money from fewer customers. I think they have chosen to move up market, charge more and walk away from the customers who are willing to go whitebox/disagg/unbundled/open/DIY. They can't win so they won't compete. Its a obvious strategy.
That means bigger enterprise customers who don't care how much money they spend will pay extra.
