Those formus were a bane of my existence, because their "technical explanations" were equally batshit crazy. (And of course none of those people was an actual engineer with knowledge in that field).
I think offgriders belong in the same crazy camp like healing crystals chicks, and antivaxxers.
I actually used to work in a solar & heat pump company.
YES it does attract a huge amount of scummy people on both sides.
Some comments have already answered on the side of sales, but it also attracts a lot of shitty clients.
How? A lot of people get greedy with free energy and/or homesteading/offgird wackos. Usually they're unable to pay the "normal" price so they chase down such scammy companies because the number they have offered fits their budget.
I have always been considered "eccentric" or a bit "odd". I made my peace with it and lived my life knowing that I'm not mentally ok.
After I emigrated to Germany and befriended new people, I realized that I have always been normal, I just didn't have hillbilly interests like everyone else around me.
I grew up in eastern europe and things work differently there.
Oftentimes the cops would fish for bribes. Cops would pick you up on the street/stop you in traffic and search you/your car/whatever in hopes of finding something to hook onto and escalate the situation further and put you in a legally difficult situation.
Then they would generously offer that they can make it all go away if somebody from your family comes and brings X amount of money.
This didn't happen just to me, in most countries of the former eastern block that's just a fact of life.
I just stopped believing in existence of deities and the existence of inherent meaning of life (not to mistake it with value of life).
The world is just a mess beyond our comprehension and we tend to attribute random events beyond our comprehension to the grand plan of things.
I do think that life is much more beautiful with the acceptance of atheism, mortality (no afterlife), personal and sexual freedom. I tend to just enjoy the moment and the life I have while I still have it knowing that this is it, this isn't a preparation for what comes next. This is it.
I'm still against mocking religion because I find it to be in poor taste, in the same vein like mocking someones gender, nationality, sexual orientation.
I'm in a very similar situation like you are. I too have started to be annoyed with the Big Tech products and the Internet in general.
I have switched to Lemmy, shut down my gmail account and opened a Proton Mail, and switched from using Google search engine to Qwant.
I too have switched to Linux Mint, and I'm loving it. TBH my IT colleauges talked me into buying refurbished Thinkpad laptop and told me to install Linux Mint. Boy am I glad I did that.
I feel you man, it must have been tough.
I'm happy for you that you got away from all that.
