Given what you’ve said, Signal is still what you want and is good for it.
There are two main issues people have with Signal:
First is that it requires a phone number to sign up. That makes some people who want it to be truly anonymous unhappy. It’s not meant to be anonymous, though. It’s meant to be private. Those aren’t the same thing.
Second is that it runs on AWS. This isn’t a problem in the sense that it’s possible for it to still retain privacy while running on AWS. Some people don’t like it because they view the dependence on the infrastructure of an American company to be a risk to availability. They also believe that it would exacerbate a security flaw if one were found.
Personally, I know these risks and still find it to be the best balance between privacy, security, and ease of use.
It’s just gone
Now, when you reload, you’ll drop the used magazine and discard all of its remaining ammo.

From reloading to custom games, today's update will give you plenty to think about.Reload When you reload in CS2, the leftover ammo in your magazine is dumped back into an essentially endless reserve supply. And so the decision to reload has never offered significant trade-offs—in a safe position with enough time, you might reload after firing a single bullet, or half a mag, or after firing down to empty, and the rest of the round would be unaffected.
It’s not like you’re reloading a magazine. It’s more like you take the magazine that’s in the gun, dropping it on the ground (including the ammo that was remaining in the magazine) and loading a new full magazine.
That part in parenthesis is what’s new. Previously, that ammo would have been returned to your reserve ammo.
