@_elena Some of the companies that host those messaging services aren't amenable to third parties accessing them and will close your accounts. That's enough of a reason (there are others) for me not to play with the bridges. At least with accounts I care about.
If you're braver than me you might wanna give Beeper a whirl. Their business model is to package a nice, customized Matrix client and lots of bridges in an easily digestible package. https://www.beeper.com
