Agreed. It was a blatantly obvious ploy from the day the book came out. Everything wireless and hackable was only thrown in because they wanted to kick hackers out of the van, especially when they changed from having to be within mutual signal strength to the godawful Noise mechanic, and they realized that, "Oh, drek, the hackers are utterly fucked. We better nerf everyone so they don't feel like they got drekked on. Except TMs, fuck those guys."
Wait, how's that work? Doesn't making everything wireless make hackers more likely to stay in the van, whereas making most things be wired-only boot them out of the van?
Before, when you needed to be in mutual signal range to hack something, you could literally hack something on the other side of the planet, if you went through international networks or satellite links. It wasn't uncommon for a hacker to spend the 'legwork' part of the run in full VR, probing a target building to get an admin account so that they could log in 'legitimately' once the run went down, limiting their exposure. The advent of Noise and Overwatch Score (combined with lower dice pools overall) meant you couldn't take the slow, safe approach any more, leading to more brute force, on the spot hacks, because that was the only way to keep a large enough pool so that you wouldn't bring down all the IC on your head.
Going back to everything being wireless, every illegal matrix action you took boosted your OS, whether it worked or not, and Noise worked against you. So to hack someone's smartgun, you'd need to be close enough that the Noise wouldn't fuck with you, and if you did too much illegal stuff between times rebooting all your gear, your OS would get high enough that GOD would drop on your head in the middle of a run.
