Well I just turned Drop In to OFF on all my devices. I refuse to sign up for Calling and Messaging as I can think of only one friend/family member that even has the ability to do it too, and I won't be asking him to jump through hoops to set this garbage up when we would rarely, if ever, use it. Major fail IMO. I live alone so the intercom feature wasn't something I could use, other than to occasionally annoy the cats. I think having to sign up for Amazon Calling and Messaging just to use the intercom is stupid, but hey we are talking about Amazon, and apparently we cannot fix stupid in their case.

I was going to set up for intercom to help others, but it just isn't worth the Amazon hassle.

ETA: IMO, intercom means talking between various rooms within a building. I've never seen nor heard of an intercom system that could target only specific people. Intercoms are room to room, not specific person to specific person. As such, why would Amazon link the intercom skill with the Calling and Messaging skill. That is totally different. Calling and Messaging needs wide area coverage and is intended for specific person to specific person communication. Amazon really needs to think things through and pull their head out of their backside. These two skills should be totally separate.
