Because Messenger (as a service) is the only way I get messages from some people. I either stop talking to those people, piss those people off by constantly cajoling them into switching services, or just talk to them the way they want to talk to me.

But Messenger (as an app) is a hateful piece of programming. I haven't had the battery issues others do, but it consumes too much memory, and causes other parts of my phone to misbehave (camera, etc.) so I'm happier not using it.

Scroll to the end of this article to see a censored version of one of the most graphic panels of the series so far (you can click through to full shot if you're up to it): http://ifanboy.com/articles/the-best-of-the-week-in-panels-11-14-2012/ It's not a sex pic, but it's a full page shot, instead of the post-stamp depictions in #12. There are other links in the comments above of some of the more explicit stuff. #11 started with a full page shot of the conception of baby/narrator in flashback. Issue #4 has a character venturing to a world called Sextillion with some of crazy stuff going on the background for about 10 pages. It's pretty obvious the trigger word here is "gay," and whatever their standards are, they are inconsistent at best.

The problem here is that MS did have a long time to put out the patch (the vulnerability was reported to them 3 months ago) and yet they did not do anything about it until it was already a zero-day exploit, and then their patch breaks applications. That doesn't look good for any group, open or closed source.
