Strangely your post makes me think of the SciFi book written by Alain Damasio - Les Furtifs. 😬

Not sure that it has been translated in English...

3. I'm guessing that Google apps would be problematic. Except those apps, I didn't have any compatibility issues, on Custom ROMs. Especially GrapheneOS, CalyxOS, LineageOS, and /e/OS.

4. On a different user, I installed banking app that would usually prevent you from using it. No problems to use the app whatsoever.

You don’t have the option of having a phone with decent specs and replaceable parts

For now it is indeed an issue. It may get better as EU imposes easily replaceable batteries for instance.

You have to have really good knowledge in tech to have private services that are on par with what the big companies offer

Well yes, because technology is complicated by nature. BigTech inject billions in making stuff simple and UX pleasant precisely to attract layman customers. Privacy-focused tech companies have less money, put a lot of effort in privacy tech, and are less mature UX-wise than classic bigTech. Customers also want more privacy, but have a hard time paying for anything. At some point the customer has to come to terms with coherence. Vote with your wallet.

You have to put up with annoying compatibility issues if you install a custom ROM on your android phone

No you don’t necessarily. LineageOS works perfectly on my Oneplus 6T.

You cannot escape apps preventing you from using them if you root your device

Yes you can. Magisk Root + Universal SafetyNet Fix v2.4.0-MOD_1.2 (by kdrag0n, modded by Displax) + editing the deny list properly.

Cars are becoming SaaS bullcrap

Use public transport when possible. Rent cars when really not possible. Problem solved.

Everything is going for a subscription model in general

I understand it’s frustrating. At the same time we either expect a constant stream of updates, or everything-IT requires regular updating if only for security purposes. Companies have employees to pay. Do you work for free?

It was outlawed out of concerns it would make us less productive

You will own nothing and you will be happy

Depending on your situation, most of your issues can be avoided by not owning a smartphone. It's extreme (by today's standards, at least), but it does work. I ditched my smartphone back in 2017 for a cheap flip phone. I can find spare parts on eBay easily. My car is older, so there is no SaaS crap in it. If I need to keep in touch with someone, we can use SMS, call each other or meet in real life. I use a Linux laptop for banking/browsing the web and I keep a physical GPS in my car in case of emergency.

and I agree with you. Privacy is pretty much gone already.

Seriously watch this video posted here: https://lemmy.world/post/2126185

If Yann is correct about how AI will work in the VERY near future, google is already dead. It has no future Personal offline open source assistant AI is near at hand. This will kill the entire digital ecosystem as it stands now. If you understand this, contextually, all the BS right now is from desperate venture capitalists trying to get as much return on investment as possible.

Get a machine with at least 16GB of VRAM on a GPU and start leaning to mess with FOSS AI. This is the next digital age.

Privacy is something we control. You don't actually NEED the conveniences. You vote with your wallet. As far as devices, I love Graphene, but I also live without anything that only comes from the proprietary google framework like the Play store. I only use open source Android apps. The Play store is not Android, it is proprietary google garbage.

Dunno, I don't use shitty apps that aren't available in F-Droid and I'm all the better for it.

Yes, we need to pass laws that prevent companies from blocking access to their services on the basis of using privacy tools. Basically apps should be able to run on any customised client device and they should only legally able to say "no" if my session is clearly demonstrating malicious interactions.

We need better consumer protection laws.
