The Control Rig is just used to increase the limits - it's the jumped in part that allows you to use the features of the vehicle/drone thanks to the rigger control. That is the part that makes this different from using any other device.
No, the Control Rig is what
lets you jump in. The bonus for jumping in is the increase in Limits which is based on the Rating of the control rig. Jumping in is just another form of control over a vehicle (drone or otherwise). Take a look at page 265, it talks about the four ways that devices can be controlled and what the difference is between them. Manual, remote, and rigger controls all work the same way and give you access to the same options. When you take control of a device, you don't use its Matrix attributes.
Now you are purposefully twisting my words. I provided the text passages that support my interpretation - that doesn't change the fact that there are no explicit rules written about the use of matrix attributes on drones because the necessary components hadn't been added to the rules yet.
I'm not twisting your words, I asked for the passage that stated that you (in any way) use the Matrix attributes of a drone when you are jumped in. You haven't provided any text that supports your idea that jumping in means that your Matrix Attributes combine.
The vehicle has a sensor limit - you use it for Electronic Warfare checks to perceive the environment
You always use the Sensor limit of the device through which you are making sensor tests, this isn't a bonus from Jumping in.
The vehicle now has a Sleaze limit - you use it for Electronic Warfare checks to jam your surroundings
Unless you formed your persona on the device, you don't make Jam signal tests through your drone. This is a basic principle of the Matrix rules and is the same reason why you can't slave a cyberdeck to a high rating commlink so that the Cyberdeck has a higher Firewall without needing to use a high point from its attribute array. You can't make Matrix actions using the attributes of slaved or even attached devices.
Not a big difference in my opinion and it definitely involves the vehicle in both cases. It's definitively an action that the drone pilot program could perform - so why shouldn't you be able as the jumped in pilot?
Further, Hacking isn't a trained skill. You can totally tell the pilot program to try and hack something as an untrained skill check. So why shouldn't you be able to do so when you are jumped in?
It is different for the reason I mentioned earlier: even when using remote control or manual controls, making Perception (or substituting Electronic Warfare) to observe your surroundings through a vehicle's sensors already uses the Sensor rating of the device as the limit. The state of being jumped in doesn't change this (it only boosts the limit, because that's what a control rig does).
Your argument is based on this statement, yes?
"In the Matrix, the icon of the device you jumped into becomes part of your persona."
That's the second-to-last sentence of the Jump Into Rigged Device Matrix action. And the problem is that you are conflating "becomes part of your persona" with sharing Matrix attributes. Most devices that are part of your PAN for example have their icons merge with your Persona/PAN icon. Just because icons merge doesn't mean that devices do. They talk about it on page 219 when they go over PANs, "Most individuals have multiple electronic devices on them at once, and having icons for each one show up would provide too much visual clutter in the Matrix. Often, what shows up instead is an icon representing an individual's personal area network."
Personally, I make it part of Matrix Perception for individual device icons to be potentially identified from the PAN icon. For example, a few extra hits on Matrix Perception when looking over a person's matrix presence will potentially reveal the presence of vision enhancement devices, cyberware, etc. even though they have become part of the person's overall persona.
The big take-away here is that a Control Rig / Jumping in never says that it gives access to anything new. It gives a bonus while using some things (the increase to limits and dice pool bonus), but doesn't give access to features that weren't previously accessible...
