This to me sounds like you are equally disrespectful of other people times as you complain that they are about yours.

What having them "bring you into the meeting at that point" means is that now everyone else has to wait the 5 minutes it takes the host to message you, wait for your arrival and then go over why they brought you in (for your benefit, and maybe everyone else's), instead of just going on with the point. I would be bothered if this would happen in one of my meetings. What you're basically saying is that your 30 minutes saved of the meeting are more important than the 5 minutes it loses for everyone else.
