Hah, yeah. Like others, I already use uBlock, and I don’t really use Facebook any more. On the other hand, I’m worried about the social implications of not using FB and Messenger. I’ve been planning to move to secure messaging apps, but it almost feels like you’re not a human if you don’t have FB. In that regard, I found switching my email provider easier. But I’ll remove my account eventually, more likely sooner than later.
I’m just adding an additional source, because I just recently read about this way of using the forward slash to create abbreviations. English Language & Usage has a good post on Stackexchange. Wikipedia says they are used for “two-letter initialisms” (a type of abbreviation). Wikipedia also provides some more examples, see here.
