| Most of these sound like reasons not to use Facebook in general. While the seen indicator is a legitimate annoyance, it's been commonplace for some years now. I don't know of a modern chat app that doesn't have it. As for the rest of your points, Facebook's money comes from ads. These concerns are not limited to chat, but using Facebook in general. As you browse the web, Facebook is tracking you and using the data to deliver more relevant ads. As you comment and make posts, Facebook uses the data to deliver more relevant ads. Every part of the service is designed to help them do this, saying that these are reasons to "not use Messenger" is missing the point. The point of using Messenger is that you're not tied to any other portion of Facebook. You just get to message friends, plain and simple. The benefit is you're not being enticed into scrolling your news feed, spammed with notifications about upcoming events etc. Plus, there are rumours they're going to bring e2e encryption in a la Whatsapp, which would pretty much squash points 2 and 3. |
Also, as an alternative, Hangouts stores my chat history in gmail (opt in), so unlike Messenger/Line/Whatsapp I have a history of all my chats on Hangouts which I actually find very useful.
That said, 99% of my friends and family are on FB Messenger
