SS7 is vulnerable to attack. However, the types off attacks on the video don’t affect Signal as it requires a pin. (Make sure you set your pin to something strong and secure)

SS7 protocol for 2G and 3G is vulnerable to man in the middle attack, easy to spy on people with. They use a walled garden approach al the primary defence mechanism and you can gain access through in for the low low price of couple of thousands of USD.
Couple of exploits are intercepting or monitoring calls and texts and triangulating position by checking what cell towers are in range.
I remember the analog days where a few keystrokes on an Ericson phone were all you needed to start listening to private conversations on the cell tower you were connected to.
My rule of thumb that grimaces in the thumbnail mean the video is playing on emotions instead of facts (i.e. is crap) has another match.
