I don't know what you consider a "serious" amount of data, but FB loads hundreds of megs of pictures and videos to your phone constantly and in the background. How much bandwidth do you think "Hey Siri, what's a conspiracy theory?" uses in comparison?
Using speech to text is very low bandwidth compared to anything else, and I'm not claiming Facebook perpetually records you to use every word you say on a server. More importantly, if they did it constantly it would easily pop up in the traffic flowing over the web proxy.
Has Facebook (or Google or Amazon) done this in the past? Yes, the technical challenges of doing it are extremely low, and legal/moral issues aside, there is a gray line between "Recording" and analyzing for keywords. Do they do it any more, most likely no. Or perhaps only in certain conditions after Zuckerberg testified about it in congress. Your phone records you constantly, thats how it knows when you say "hey Siri" - but it doesn't spring into action until the wake words are sent.
Again, I was building big data research tools. Every Google/Apple public private API that could scrub data worth anything was something I've had to go through at some point in time. The machine learning alone that can be gathered from your images you post gives away just as much data as what hashtags you use (by tagging images, we effectively become classifiers for ML algorithms - we do the work for them just like a captcha).
99.9% of this isn't nefarious, they just want to sell you more stuff - but knowing that all these data collection sources exist and turning off those which you don't absolutely need becomes more and more valuable. "Hey we need access to your camera and microphone, how about one of these silly AR masks that make you look like batman in exchange for that data?"
