Improvement in computing makes me hack a 1920s typewriter wirelessly!

Except a 1920's typewriter isn't a high-tech electronic device.
Before you dismiss this out of hand, consider the plausibility of forcing a 1980s electronic word processor to emit a line of text by bombarding it with a signal. Does it sound impractical and potentially very difficult? Yes. But given powerful enough technology would it be impossible? I don't know.
But what we're talking about here is futuretech affecting futuretech.

But they aren't running around with all their gear fully immersed in a wireless matrix soup to start with. That requirement is being added to punish players for not running wireless to start wit. So the logic is still flawed.
Their gear is fully immersed in a wireless matrix soup, because everything is -- that's the point of the wireless Matrix, it's ubiquitous, at least in civilized areas. I'm immersed in wireless internet signal where I'm sitting because I have a wireless internet router bombarding me with wireless internet signals. They occasionally tell my phone to do stuff because my phone is set up to easily interpret those signals.
Now I'm going to make a comparison:
You have a tape deck. The tape deck is "dumb" in that you have to push buttons to make physical connections to get it to route electricity the right way to get things to work. No level of electromagnetic induction is going to make the tape deck switch on by itself.
Now you have an iPod that has no mechanical switches except for an off button. Everything is interpreted electrical signals routed through a central processor. It's conceivable that you could hit it with carefully targeted signals to induce the proper electromagnetic effect within its circuitry to get it to do something without touching it. Conceivable, but not really plausible with current technology.
Now in the advanced cybertech future, imagine that such a device exists and running special programs can suss out and induce the proper response in cyberware that was never originally designed to accept external signals. This level of technology would make every single formerly secure system vulnerable to brute hacking attacks (remember, it's just smacking the cyberware with a signal, not establishing a two-way connection) in sort of the way an electrical device would be vulnerable to an EMP (external electromagnetic signal just overwhelming and overloading the circuitry) except in this case it would carry an instruction: shut down, run amok, whatever.
The only two responses to this sort of threat would be
1) Make cyberware dumber. Sorry, you can't have an internal processor active, because it's vulnerable to our new EMP-esque instruction bomb technology. Baseline functionality can be retained. Cybereyes can transmit along the optic nerve connection, but you can't run the software needed for a full DNI to control all those special features. Wireless Reflexes still make you faster because the nerve connections are upgraded, but it can't coordinate with Reaction Enhancer systems because the two need heavy processing power to keep you from accidentally leaping off a building when you really intend to sidestep just a little.
2) Create an external system watchdog that can handle these signals and ignore them if they're not fully authenticated by the system. Everything gets linked up via the commlink, and the commlink detects the new information attack and instructs your Wireless Reflexes to keep talking to the Reaction Enhancers and ignore that new command to make your legs start going all Riverdance.
The end result is that cyberware gets options for #1 and #2 depending on the preferences of the user -- you can keep your 'ware running on tortoise mode for security and flip it to fully active mode integrated into your PAN for linked/active mode if you need it.
It seems to me that this is exactly what the new rules have done, they just haven't made a similar justification by introducing the necessary threat that would completely kill off the old-styled cyberware. Eg, we got the endpoint of my little scenario without the meat of it.
