Does the equipment stop working?
I don’t understand how any country in the world is using equipment that can be turned off by the manufacturer. Infrastructure, communications, farming, etc. should all be run with non-revocable licenses. Make it the law.
Cisco IOS/IOS-XE routers and switches will complain that you haven't licensed them correctly, but it doesn't impact functionality.
Cisco shot both it's feet years ago with an unpopular "SMART Licensing" scheme. One of my proudest moments as a net tech was the shocked silence when I told a room of Cisco employees that we weren't upgrading our 3850s past 16.6 (or something) because we refused to deal with their SMART licensing. They came up with a solution and we ended up upgrading (there was a feature in a later version that we wanted).
In the past, there were different software images for different feature sets. If you could get ahold of an image you didn't pay for, it would just work and you'd have functionality that wasn't licensed.
In the really distant past, this worked but not well because you'd need specialized hardware for things like fast encryption for VPN. So, if you didn't pay for the securityk9 license and used the 2811 without a VPN module, it would work but not well.
Anyways, I'm not aware of Cisco having any ability to brick customer equipment. I read this article as saying they destroyed their own property in branches and warehouses within the Russian Federation.
The ability to remotely disable equipment is essential in order to allow for cheaper financing plans, to make sure customers don't steal stuff they haven't finished paying for, or that they've only been leasing.
Sure, you could pass a law prohibiting that. But then customers have to pay a whole lot more in financing/leasing because there's much more incentive to stop payment but keep the equipment, and repossessing the equipment gets messy. (You can move/hide a tractor or a router much more easily than you can move a house.)
Not that I have any pity towards Russia, but, say, China can also do this in the case of war.
Same with some foreign governments moving to private-label Linux variants to reduce reliance on [US-produced] Windows.
Next is TikTok, to eliminate foreign software with large domestic deployment.
Unless we backdoor Android/iOS, the US doesn't have too many more strings to pull.
Presumably they weren't already using those other options before because they were worse for some reason or another, and so it still hurts to have to switch. Plus, having fewer options may mean it's harder to negotiate a good deal.
Breaking the inertia on a whole bunch of geopolitical norms has been the largest result of all this mess.
Freezing foreign reserves and restricting access to international financial messaging systems etc is probably the biggest change to the status quo and the reverberations of that have set in motion huge changes.
The unilateral sanctions have been levied before, but usually only against "backwater" places that have no chance to fight back and thus most countries with a functional military and economy were never too scared of it.
Applying the same sort of doctrine against a functional (even if barely so) nation like Russia has set off alarm bells in every nation that doesn't identify as "Western". This is why you are seeing actual progress towards international trade being settled in non-USD currencies. The breaking of petrodollar and the shifting allegiance of OPEC away from the West after ~40 years of tenuous "cooperation" is also a big consequence of this.
It's very unclear waters ahead now. I'm not really sure breaking all these norms was worth it vs just sending traditional support and utilising traditional sanctions. If Russia was expelled from Ukraine within months of enacting it then I might have had a different view but now I'm sceptical this was a good idea.
In the best of times, in the best of places, you'd be able to do that. Decommission the hardware in use, pack it all up, ship it wherever.
It is not the best of times in Russia and it was never the best of places.
In the best of times while operating in an adversarial market (to put it diplomatically), you have to know you're doing this well in advance and slowly phase out the equipment. Some of it is likely physically installed in the locations. And you have to do this while essentially receiving no new equipment. Which you could do by just faking shipments and manifests. But you're effectively smuggling at this point.
Now, with everything going on. You have to worry about Russia just sort of claiming your hardware/business/people and daring you to come get it. You get your people out and torch everything you can on your way out.

1- That involves added costs that you may or may not recoup (read sibling comment about Russia "not allowing it" which doesn't seem out of hand). So if you don't want it in the current State's hands, and you can't reliably export them, destruction might be the right choice. 2- Part of the goal may be the headline. Either good press for Cisco or bad press for Russia, but visibility can be a goal as well.
But for serious, likely too risky to have the potential for anything that can fall into a sanctioned country’s hands. Just destroy it and write it off.
I think something got lost in translation here.
Just FYI.
I can't imagine this is anything more than a good opportunity to cut bait and get a good pres release on the write-off
