All is about threat model. I really would love to switch to firefox but afaik it's less secure. So who would hurt me more, so random dude or corporation? My choice is simple.

It's the same with all messengers. I use facebook messenger (because everybody around me use it) and i know that they collect a lot of data (and have acess to my chats). For me, still threat isn't facebook but my acquaintances who use weak password, so they're easy target (and my messages would be compromised).

We have to change our mind about computers. Everything can be exploited and used against us.
