I think I'm very lucky that I didn't subscribe to many of the giants. I suspect it's a lot easier for me to live without FB because I've never had it. Same with not having a smartphone. I often wonder if I should get one, but I can't imagine how having one would make my life better - or at least better enough to justify the financial burden.
But I'm of a generation that knew what it was like not to have the internet. HTML became a real thing when I was in my teens, and for many, many years, it was hammered home that we were not to trust the world we find online. Be very careful giving out your data because your personal data is the only thing that makes you unique on the internet. Your personal data is the most powerful weapon that can be used against you. Most importantly, if someone wants to give you something "free" in exchange for you using it, then there must be a reason. We live in a capitalist centric world. Nothing is "free" without good reason. When a company or corporation is big enough to have that name, then be certain they are making a profit out of you using the "free" thing.
That is the belief system that was ingrained in me as I learned to use the internet and I've been very careful to read the terms of service of any big corporation I interact with. (have a read of the FB fine print if you ever want to lose sleep). I do utilize some services of The Tech Giants but I'm very aware of what data I give them.
But to be frank, most of these things cost money. Smartphones. Smart speakers. I have better things to spend my money on.
Although, this is tempting
Or maybe that you can now guess my age, I should be getting something like this?
