Oh how I hate technology !!!

Those of you who know me fairly well,
no doubt have a giggle anytime I ask daft tech questions.
If for no ôther reason than the answers would be self-evident to your average 9 year old !
As I sit here. My PC is 'updating'....Again !
I'm a bit concerned about the number of big corporations that you have to deal with just to do the simple jobs in life !
I-cloud. & I-tunes necessitate THIS particular update.
This concerns me for as far as I know, I don't use EITHER !
Yet they both want permission to 'Make changes to my computer'.
I'm used to apple sending me 200 pages of nonsensical legal jargon that I have to 'o.k' before being able to use my phone every so often.
But when you think about it, Google; Apple; Facebook; Amazon and probably a few others, ALL want your personal details.
Why ?
Where is the benefit to me in giving you my personal details ???
Yet they ALL insist on it.
So. I avoid Google.
I've left EVERY group I joined on Facebook. I use Amazon ONLY if I can't find what I want elsewhere.
Am I alone in feeling like I'M the commodity ???
