If it's a FAANG talking in specific about anything work/employer related - unless you are working on OSS stuff; talking about new APIs, etc (as you'll see many engineers on twitter, etc after I/O, WWDC, etc) - is very much frowned* on. Certainly any such presence would need to take care to avoid the appearance of being a company rep, etc. There are very few companies that are likely to be ok with random employees talking to media, maybe not the same result as a FAANG, but I can't see avoiding any repercussions (e.g if a bank employee goes off and talks to the news presenting themselves as a rep from the bank, I don't see that going well) * frowned == new job
